  • 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

    Crown K1 Balanced Current Amplifier (3 available) 350 watts/channel

    Crown K1 Balanced Current Amplifier (3 available) as of 9/24 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.

  • 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
