  • Dynaco Stereo 120 (3) and PAT 4 preamp

    Dynaco Stereo 120 (3) and PAT 4 preamp

    You can purchase each item individually. We have one 120 that we just replaced the coupling caps and resoldered the board as needed. That's $250 Inquire The Dynaco Stereo 120 is an all silicon transistor basic power amplifier for use with separate preamplifiers such as the Dynaco PAT-4 or PAT-5, or for use with tape recorders or tuners such as the FM-5 or AF-6, which have their own volume controls. The unit contains two 60 watt amplifiers on one chassis with a common power supply. Although the Stereo 120 is a solid state device, containing transistors and similar semiconductors, it has been designed to be used under normal conditions without special safety precautions, just as if it were a high grade tube amplifier. Thus it can be connected to source and speaker components and used with confidence in all conventional arrangements. There are no circuit breakers, speaker fuses, or other resettable devices to impede the use of the Stereo 120 under any reasonable conditions of use or abuse. This is achieved by using novel circuits (on which patents are pending) which automatically and instantly protect the amplifier. Specifications Power output: 60 watts per channel into 8Ω (stereo) Frequency response: 5Hz to 100kHz Total harmonic distortion: 0.5% Damping factor: 40 Input sensitivity: 1.5V Signal to noise ratio: 95dB Speaker load impedance: 4Ω to 16Ω Semiconductors: 15 x transistors, 15 x diodes Dimensions: 13 x 10.5 x 4 inches Weight: 20lbs Learn More

    Top of the line. Cary 211M mono amplifier, used pair in excellent condition original crates and double boxes. Photos are without tubes but you get those packed separately. It is well known that using monoblock amplifiers, as opposed to both channels together as a stereo chassis, is the best way to get powerful and lifelike music. By using separate power supplies that can be much more massive, each amplifier can have more dynamic power and be quieter. Keeping two separate amplifiers also makes any inter-channel crosstalk in the amplifiers impossible, so separation is better, meaning your soundstage and musical imaging will be larger and more well-defined. The simple act of separating the two channels provides a lot of distinct advantages, but also increases the investment because of needing to double up on power supplies and chassis parts. Learn More

    Crown K1 Balanced Current Amplifier (4 available) 350 watts/channel

    Crown K1 Balanced Current Amplifier (4 available) in 3/23 consumer used only Crown K1 Amplifier at a Glance: Balanced Current Amplifier technology ensures thermal stability without a fan! Delivers 350 watts at 8 Ohms, up to 1500 watts (bridged) at 4 Ohms Incredibly flat frequency response for compromise-free audio Massive power with one tenth the heat! The K1 amp from Crown is the first amplifier to take advantage of Crown's new Balanced Current Amplifier technology. This technology yields extremely efficient power amplification while generating just one-tenth the heat of conventional amplifiers. In fact, the powerful K1 Amplifier can deliver an amazing 750 watts per channel into 2 Ohms (and that's a very solid 2 Ohms)! As a result the amp can put out clean, uncolored power without the use of a fan. No fan means the K1 runs quietly and cleanly, takes up less space in a rack and requires less maintenance. The K1 also boasts advanced circuitry protection that guards against DC, mismatched loads, internal faults and high frequency overloads. Crown is so confident of the K1's stability that it's backed by a three-year no fault warranty! Power to spare, no matter what your configuration The Crown K1 Amplifier is rated to deliver 350 watts per channel at 8 Ohms, 550 watts into 4 Ohms or 750 watts per channel into 2 Ohms. In addition, in bridged mode the K1 has a capability of 1100 watts at 8 Ohms or 1500 watts at 4 Ohms - all while running without a fan! The K1 is cool, clean and quiet. Legendary Crown frequency response Crown amps have a long history of providing crystal-clear audio response in critical listening situations, and the K1 Amplifier is no exception. Flat frequency response: (+/- .25 dB) from 20Hz to 20kHz ensure you get out of the K1 exactly what you put into it! Crown K1 Amplifier Features: Soft Start (Keeps amp from drawing large currents when first turned on) Switchable Input Sensitivity (1.4V or 26dB) Mono mode switches: Bridged, Y (parallel) or both (for daisy chaining) Balanced XLR and 1/4" inputs 5-way binding posts Channel 1 and Channel 2 gain controls with notched settings LEDS: Thermal (Warns of need to dissipate heat), Clip (Warns of distortion in the amp), IOC (Input / Output Comparator: Warns of distortion at 1/30th the level of clipping by comparing the actual waveforms of the input to the output), Signal (glows when output signal is present), Enable (Indicates Power status) Frequency Response: +/- .25 dB for 20Hz - 20kHz Power Output (per Channel): 750 watts into 2 Ohms, 550 watts into 4 Ohms, 350 watts into 8 Ohms Bridged (mono) power: 1500 watts at 4 Ohms, 1100 watts at 8 Ohms Signal-to Noise (A Weighted): >100dB below rated power Damping Factor: >3000 from 10 to 400Hz Input Impedance: Nominally 20KOhms balanced, 10KOhms unbalanced Passive convection cooling allows amplifier to drive 2 Ohm load at 8db into clip in 104 degree environment!

  • Crown Reference 1

    Crown Reference 1

    Crown Reference 1 in service 9/21 Inquire before purchasing Reference I (120 V, 60 Hz models) The Crown® Studio Reference I power amplifier shall be a solid-state two-channel model employing multi-mode (AB+B) grounded bridge(TM) output circuitry with a variable impedance (VZ) power supply for each channel. The outputs shall be switchable as stereo, bridged-mono or parallel-mono modes of operation. The bridged-mono mode shall bridge the outputs to provide increased output voltage. The parallel-mono mode shall parallel the outputs to provide increased output current. The output impedance of each channel shall be less than 10 milliohms in series with less than 2 microhenries in stereo mode. The variable impedance power supplies shall reduce unnecessary voltage across the output devices by automatically switching to a parallel mode when less voltage is required by the output circuitry and to a series mode when more voltage is required. The amplifier shall contain protection circuitry which limits the drive level placed on the output devices before their SOA (Safe Operating Area) is exceeded. This protection circuitry shall calculate the instantaneous voltage across and current through the output devices while factoring in their simulated junction temperatures to predict how close they are to their operating limits. This protection will be called “ODEP.” The amplifier shall contain controlled slew-rate voltage circuitry to protect it against radio frequency interference burnouts. It shall also be protected from current overload at its output stage. The slew rate of the amplifier shall be greater than 30 volts per microsecond in stereo mode. The amplifier shall temporarily go into a stand-by mode if its power transformer becomes excessively hot and shall automatically resume normal operation once it has cooled to a safe operating temperature. Front-panel controls shall include an enable on/off switch and a detented input level control for each channel. Rear-mounted controls shall include a ground lift switch to isolate the signal ground from the chassis ground, a switch which selects between stereo, bridged-mono and parallel-mono modes of operation and a reset switch for the AC mains circuit breaker. Internal controls shall include an input sensitivity switch to select between 0.775 V, 1.4 V or a fixed voltage gain of 26 dB for full rated output. A Crown P.I.P. and P.I.P.2-compatible expansion connector shall be provided behind an access panel in the rear to accept auxiliary input modules. It shall be fully compatible with the Crown IQ System. Front panel indicators shall include an amber power enable indicator, an amber ODEP protection system indicator for each channel which shall normally be illuminated to confirm the availability of reserve thermodynamic energy and which shall dim in proportion to limiting when the power demands of the output stages have been exceeded, a green IOC indicator for each channel, and a green Signal indicator for each channel which shall normally flash at moderate intensity to show the presence of an audio signal. The power amplifier shall meet or exceed the following performance criteria. Input sensitivity for rated output: 26 dB voltage gain (unbalanced). Rated FTC output in stereo mode with less than 0.1% THD: 780watts per channel (20 Hz to 20 kHz) into 8 ohms. Hum and noise: at least 120 dB (A weighted) below full rated output power. Phase response: +5 to –15 degrees from 20 Hz to 20 kHz at 1 watt. Frequency response: 20 Hz to 20 kHz, 0.1 dB at 1 watt into 8 ohms per channel in stereo mode. Damping factor: greater than 20,000 from 10 to 200 Hz into 8 ohms. Intermodulation distortion (SMPTE): less than 0.005% from full bandwidth power to 78 watts rising linearly to better than 70 dB at 20 kHz. Harmonic distortion: less than 0.02% at rated low-distortion 1 kHz power. The amplifier shall be safe when driving any kind of load—even highly reactive ones. The power requirements shall be 120 VAC at 60 Hz. At idle, the amplifier shall draw 90 watts or less. The amplifier chassis shall be constructed of steel with a durable black finish and shall be designed for flow-through fan-assisted ventilation from the front panel to the side panels. The amplifier shall have an aluminum front panel with super-gloss Imron finish and Lexan overlay. The dimensions of the amplifier shall allow for 19 inch (48.3 cm) EIA standard (RS- 310-B) rack mounting. The amplifier shall be 7 inches (17.8 cm) tall, 16 inches (40.6 cm) deep behind the rack-mounting surface, and 2.75 inches (7 cm) in front of the rack-mounting surface. The amplifier shall weigh 60 pounds, 11 ounces (27.6 kg) and shall have a center of gravity approximately 6 inches (15.2 cm) behind the front panel. The amplifier shall be designated the Crown Studio Reference Learn More

  • Thule Audio SPIRIT PA100 power amplifier

    Thule Audio SPIRIT PA100 power amplifier

    Thule Audio Spirit PA100 power amplifier Thule Audio is a Danish company, specializing in audio equipment, ranging from basic entry level models, to models which are High End stuff. The product line is well thought out, and as we shall see, very rationally conceived and executed. For other reviews of Thule Audio products, look over the site. Both cases are virtually identical, and share the overall look of the entire Thule Spirit range. They are made of uncommonly thick, heavy and well finished cases, while front panels are made from 8mm thick aluminium, machined so that they have a gentle slope. In the center, one will find a "gold" knob in case of the preamp, and a decoration in case of the amp. The preamp has an alphanumeric display above the knob, which provides the user with all relevant information on power on, volume and input status in red LEDs. All this is fully remote controllable, and a remote control unit is supplied. The power amp is a very simple affair, with only a red LED power on indicator on its front side. Both units have rocker power on/off switches at the back, as they're intended to be left in standby mode all the time. [Thule PR 100 inside view] Both units share much more common componentry that I would have imagined. Both use toroidal power supplies, where the amp's toroid is rated at 500VA, while the preamp's toroid is rated at 300VA. No, you're not seeing things, it's not a typo error, I did say 300VA. That's enough for a 2x75W/8 Ohm power amplifier, let alone a simple preamp. In fact, the preamp is EXACTLY the same as the IA60 integrated amplifier, minus the power amp circuitry and heat sinks. Put another way, the preamp consists of the preamp section of the IA60 integrated. Hence the 300VA toroidal transformer - that's what they use in IA60 (see review on this site). The power amp, on the other hand, is once more the same board, but minus the preamp circuitry and with heftier power supplies - bigger transformer, and 4x10.000uF capacitors, instead of just 2x10.000uF. This is no accident, this is rational thinking. Use the same board, use the same case, use the same power supplies and you increase the numbers of your serial production, thus pushing the cost per unit down. The only thing that spoils the show is the preamp's price - it's simpler than the integrated model, but it's not only not cheaper, it's actually somewhat more expensive. That is most odd, I must say - probably for "complex marketing reasons" (a phrase I first heard in the early seventies, and it's gotten worse since then). You still have 5 line level inputs, with no option for a phono RIAA board of any kind. You still don't have a headphone output - somebody should inform the Scandinavian audio industry that headphones have been invented some decades ago, they seem to have collectively overslept that event. As usual, all input and output sockets are gold plated. Like elsewhere in Thule's product portfolio, volume and balance are controlled by a ladder of laser trimmed resistors, contained within an LM1792 digital volume control, a good point - no mechanics, no wear and tear, no aging, unparalleled precision. The amp is rated at 2x100W/8 ohms and 170W/4 Ohms - that should be enough for most of us. It has an RCA Cinch and a balanced XLR input, just as the preamp has the same outputs. Acting on logic and Thule's recommendation, I used balanced lines to link the two, except when using other units. Learn More

  • Dynaco ST 150 power amplifier

    Dynaco ST 150 power amplifier

    Dynaco ST 150 power amplifier The Dynaco Stereo 150 is a basic two channel power amplifier employing all silicon semiconductors. They include 24 transistors, 2 zener diodes, 16 diodes, and 2 thermal sensors. The output circuitry is of the full complementary symmetry design. The entire amplifier, except for an input network, is direct coupled. It's measured distortion levels approach the threshold of much laboratory test equipment, not only at the commonly specified full power ratings, but more importantly at very low power outputs as well. This is the result of circuit techniques which eliminate any discernible crossover notch at low levels, and contributes to the Stereo 150's freedom from listening fatigue. It's accurate, uncoloured sonics have been achieved on a wide variety of loudspeaker loads, including electrostatics and multiple drivers with complex crossovers. The design of a very fine power amplifier implies the necessity of several protection techniques for the amplifier, and for the speaker load. In addition to the AC line fuse, four separate B+ fuses are supplied. Electronic volt-amp limiting ensures safe operation of the output transistors, and a thermal sensor mounted directly on each output stage reduces the input if high temperature occurs. An unusually large radiating area for the heat fins, which are coupled to an aluminium back panel, form a highly efficient heat sink. Speaker fuses protect the load. The Stereo 150 has been designed as two independent 75 watts (at 8 ohms) amplifying channels with a common power supply having a high degree of inherent regulation. In addition, where higher powers or higher volt-amp capabilities are required for lower load impedances, easy internal restrapping permits monophonic operation for 150 watts output (at 8 ohms). An accessory kit is planned at additional cost for two output meters and meter switching, which includes alternative inserts for the front panel. Specifications Power output: 75 watts per channel into 8Ω (stereo) Frequency response: 20Hz to 20kHz Total harmonic distortion: 0.25% Damping factor: 50 Input sensitivity: 1V Signal to noise ratio: 95dB Speaker load impedance: 4Ω to 16Ω Semiconductors: 24 x transistors, 2 x zener diodes, 16 x diodes, 2 x thermal sensors Dimensions: 14.5 x 13.75 x 7 inches Weight: 29lbs Learn More

  • Conrad Johnson Classic 62 - 60w/ch stereo, vacuum-tube

    Conrad Johnson Classic 62 - 60w/ch stereo, vacuum-tube

    The conrad-johnson design team is committed to adapting the advances from our state-of-the-art pursuits to more affordable offerings accessible to a wider range of music lovers. This resolve is clearly evident in our new range of Classic amplifiers. Borrowing heavily on the technology of our flagship ART amplifier, the Classic amplifiers preserve the distinctive tonal character of individual instruments and voices, with each clearly located within the overall acoustical environment of the original recording. Musical transients are reproduced with realistic impact, but without artificial enhancement. Like their more costly siblings, the Classic amplifiers capture the emotional impact of the live event, never getting between the listener and the musical performance. There really is no mystery to our chosen path to outstanding musical performance: best results come from simple circuits executed with quality parts. The circuit design for the Classic amplifiers is about as simple as possible, employing just seven vacuum tubes in the Classic Sixty-Two. Single-ended triode voltage gain and inverter stages are coupled to an output stage comprised of a single pair of ultra-linear operated EL34 tubes for each channel. The Classic One-Twenty adds a second pair of output tubes to each channel to achieve twice the output power. Simple but highly effective discrete voltage regulators supply rock-solid stable DC voltage to the critical voltage gain and inverter stages. And speaking of simple, maintenance of the Classic amplifiers could hardly be easier: the owner need only make a simple bias adjustment using the built in bias indicators when installing fresh output tubes. The use of premium quality component parts is the other half of the conrad-johnson recipe for superior musicality. In this area as well, the Classic amplifiers are leaders in their class. Precision, metal-film resistors yield low noise performance for greatest clarity. Polypropylene and polystyrene capacitors, chosen to achieve a high degree of temporal accuracy, are specified for both the audio cir¬cuits and the regulated plate voltage supplies for the input and inverter stages. The result is an exceptional range of dynamics – reproducing both subtle variations in level as well as dramatic loud crescendos. Our proprietary trans-spectral wide-bandwidth output transformers contribute importantly to the extended, “airy” highs that help distinguish the Classic amplifiers from ordinary tube amplifiers. The base model Classic amplifiers offer an ideal introduction to the joys of modern tube amplifiers, while the ease of use, low maintenance costs, and reliability will be a revelation for those who have only experienced “entry-level” tube gear. Those who wish to take the experience a step further will want to investigate the upgraded Classic Sixty-Two SE and Classic One-Twenty SE amplifiers. These special edition versions upgrade the output tubes to KT120s and incorporate CJD Teflon Capacitors and ultra high-performance metal foil resistors in strategic applications in the circuit. Any of the Classic amplifier models are sure to rekindle your passion for enjoying great music in your home. Learn More

  • Audio Research VS110

    Audio Research VS110

    Audio Research VS110 2 available price is for each unused since 2014 in 11/2021 Given the enthusiastic response to the appearance and sonic peformance of the VS55, you will be happy to know that a more powerful version of this remarkable amplifier is now available: the VS110, rated at 100 WPC. This brings vacuum-tube musicality as only Audio Research can do it to a new power level and price. The chassis, circuit layout and feature set of the VS110 are almost identical to the VS55, but scaled up to accomodate the greater power output. The chassis itself measures 17 ½" W by 19" D, and features an anodized, natural-finish top plate labeled with tube location/type, output-tube bias access points and the inset Audio Research logo. The chassis front holds a rocker-style power switch and green LED "on" indicator. The chassis rear provides the 0-4-8 ohm 5-way binding posts, voltmeter test points for setting bias, a 12V in/out trigger and a detachable 14-gauge A.C. line cord with IEC socket. There are two matched pair of 6550C output tubes in each channel, fed by two 6NIP triode driver/followers, which in turn are fed by a single 6NIP input tube. Storage capacity of the bulk power supply is double that of the VS55 and uses the same type of fast, low-ESR Nichicon® capacitors. The simplicity and purity of the audio circuit is a proven performer, but now it can deliver more power for larger speakers in larger rooms. Like the VS55, the VS110 ships in one color /chassis configuration, black with natural anodized top plate. A perforated cage-type cover is optional, and must be ordered as a separate item. The sonic signature of the VS110 is very much like that of the VS55, but with more robust dynamics, greater bass impact and power, and a larger soundstage. With so much similarity between these two amplifiers, choosing the right amplifier is simple. The look, the feature set, the circuit types are identical: it is simply a question of how much power you need or want. The VS110 combines classic tube-amplifier appeal with robust power, genuine musicality and solid value. And don't forget Audio Research's unmatched record for long-term product support - a key measure of keeping customers satisfied, decade after decade. POWER OUTPUT 100 watts per channel continuous from 20Hz to 20kHz. 1kHz total harmonic distortion typically 0.5% at 100 watts, below .05% at 1 watt. Approximate actual power available at "clipping": 120 watts (1kHz) (Note that the actual RMS power output is dependent upon both line voltage and "condition" ie: if power line has high distortion, maximum power will be affected adversely, although from a listening standpoint this is not very critical.)
