  • Thule Audio PA100 power amplifier

    Thule Audio PA100 power amplifier

    Thule Audio 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

    Mark Levinson 333 power amplifier

    Mark Levinson 333 power amplifier the aesthetic of the Mark Levinson No. 333 power amplifier is stunning. The curved silver face plate with black ridged heat-sinks make the No. 333 a conversation piece even for non-audiophiles. The attention to detail in the design of the 300 series amps is phenomenal. For example, the amp stays powered down in standby mode until your ready to listen. In ten seconds the amp powers up the power supply gently, so that the amp is at optimum performance quickly. The standby feature allows the 300 series amps the ability to conserve power while reducing wear and tear on the amp during charge-discharge cycles. It also allows remote power switching from Levinson and Proceed preamps and control systems. The Mark Levinson No. 333 is outfitted with the single best speaker connectors on the market. They accept various sizes of cable but need no wrench to tighten. They are ergonomically designed so that absolutely anyone can perfectly tighten their speaker cables to the perfect pressure without tools. A link to the Madrigal site for more technical details on the Mark Levinson 300 series amps is found at the end of this review. 300w/ch @8 ohms; 600w/ch @4 ohms; 1,200w/ch @2 ohms Learn More

    Linn AV 5105 Stereo Power Amplifier

    Linn AV 5105 Stereo Power Amplifier The Linn AV 5105 Stereo Power Amplifier is intended for use in high performance audio and audio/video systems. It combines high output power, ruggedness, and ease of use with our passion for quality. It draws on years of experience of designing and making high quality audio power amplifiers. Inside the compact case are two completely independent electrically isolated channels with fully regulated power supplies giving ‘dual mono’ performance. The signal path is DC coupled and servo controlled for the lowest distortion, cleanest, least colored sound. The output stage is highly derated for cool, reliable operation, and the protection circuitry protects extensively against accidents or abuse. A signal sensing circuit detects the presence of audio above a very low level and turns on the main power supplies to the amplifier, bringing the power amplifier channel from a very low standby power consumption to full operation. It reverts to the standby condition a few minutes after the input signal disappears. This is particularly useful in multi-channel surround sound systems. The AV 5105 accepts the Linn active crossover modules, automatically detecting their presence and switching them in circuit as soon as they are plugged in. This makes playback system upgrades easy. Type Two fully independent channels, isolated from each other and chassis (earth). Fully regulated dual power supplies per channel. Inputs Dual RCA Phono (Line in/out) Outputs Four pairs per channel Protection Fully protected into any load; overload, over-temperature, full short and overdrive protection Remote control Signal-sensing auto switch-on/off for energy conservation or remote operation Output power 100W/channel/8Ω, 200W/Channel/4Ω Input signal 1.05V rms for maximum output Output voltage 28.3V rms maximum Gain x27 (28.6dB) Input impedance 4700Ω Frequency response (-3dB) 2Hz-50kHz Output offset 150μV rms Mains supply 220V–240V T3.15A antisurge, 100V–120V T6.3A antisurge Standby power consumption Learn More

    Krell KSA150 classic Krell amplifier, Great amp to get into high end audio with. 90 days parts and labor warranty The latest generation of high-resolution source components and speakers places new demands on the power amplifier. The Krell KSA 150 and KSA-250 meet these challenges with fresh design sophistication and long-term value. Both products can drive any speaker with an effortless quality that makes their power seem endless. Extreme clarity is maintained at all power levels. They both utilize Krell refined high-bias Class A and direct-coupled circuitry from input to output. Their power supplies and output stages are massive. High voltage rails with extensive regulation are provided for the input circuitry. All materials and electronic components are of the finest quality and operate within their optimum performance ranges. Virtually all hand wiring has been eliminated, resulting in a dramatic improvement in sonic clarity. The KSA-150 and KSA-250 both utilize Class A circuitry throughout the audio and power supply regulation stages. Class A gain stages deliver excellent sonic performance under diverse conditions because all active components are turned on at all times. This allows each component to operate in its most linear and precise regions. The amplifiers are able to respond to the full range of input signals with equal accuracy. The KSA-150 and the KSA-250 are conservatively rated at 150 and 250 watts per channel into 8 ohms, respectively. The 150 will actually generate 220 watts into 8 ohms, and the 250 will generate 320 watts into 8 ohms. The 8-ohm power ratings do not account for the amplifiers superb sonic performance nor describe their maximum power. The Krell definition of power and the ability to drive low impedances is that the output must double into successively low impedances. The immense power supplies in both products allow them to double their power into one ohm. There are many advances in thermal construction and control circuitry in the KSA -150 and KSA -250. All heat bearing structural components and external heat sinks have been designed in-house to improve thermal tracking and cooling. This construction provides very low thermal resistance between the output transistors and the heat sinks, resulting in superior thermal tracking. It also results in a considerable reduction in overall size. Greater amplifier life expectancy is an added design benefit. Automatic self-adjusting bias and DC offset control circuitry have been developed for the KSA-150 and the KSA-250. These circuits compel the amplifiers to conform to their intended operational parameters under all AC mains conditions. Learn More

    Krell KSA100 MK II

    Krell KSA100 MK II excellent cosmetics, there are some green markings in the picture which were removed. We can ship this in your desired voltage Description provided by highendclassics.com: The Krell KSA-100 Class A poweramplifier was the first stereo amplifier from Krell Audio Industries. At the start of the eighties Connecticut witnessed the birth of another highend audio company within its stateborders: Krell Industies. ‘Class A power to the people’ could have been one of the inspiring thoughts for Daniel D’Agostino chief designer of Krell Industries. Of course there were already some Class A designs in the domain of the power amplifier but most and probably all of them were confined to relatively small powerratings. Even the huge monaural Class A amplifier from Levinson, the ML-2’s, could only muster 30 to 40 Watts of power at 8 Ohms. Other noteworthy low power Class A designs were John Bedini’s 25/25 Class A amp and Jean Hiraga’s ‘Hiraga Classe A’. The only high power Class A amp in those days was a stereo 125 Watt Class A design from the SUMO electric company named ‘The Gold’ designed by James Bongiorno. D’Agostino envisioned and designed an array of high powered Class A amps in which the KSA-100 (abbreviation KSA stands for Krell Stereo Amplifier) was the most powerful stereo amplifier rated at 100 Watts Class A power at 8 Ohms. Technical The KSA-100 is a configuration of two completely separated amps only sharing the same huge chassis. Each amp has its own powersupply (one Avel Lindberg 1250 VA toroidal, two 40,000 uF Sprague or Mallory large cans per channel), driverboard and poweroutputsection. Another so called true dual mono design was the ML-3 from Levinson but this amp was biased in AB mode. To get rid of all the Class A generated heat from the outputsection Krell opted for forced cooling with Papst fans blowing down (the MK II version blew upwards in sync with the natural convection flow of heat) trough circular arranged heatsinks with eight TO3 encased powertransistors per channel attached to it. As a matter of fact the ‘The Gold’ from the SUMO company also used fans to cool down the amp. Using active cooling instead of natural convection kept size and cost in check because huge expansive heatsinks would be needed to drop off the 650 Watts continuous power consumption. Seven years later Krell did make huge convection cooled mono-amps as their reference series (KRS-100 & KRS-200) with the same Class A output but with a significant raise in price and weight compared to the forced cooled versions. Although Krell has always been strongly associated with Class A biasing it’s their ability to drive extremely tough loads, like the renowned amplifier killer the Apogee Scintilla (1 Ohm version) fullrange ribbonspeaker, that really illustrated the kind of DNA a Krell was made of. Only a few other amplifiers in this era, and most of them were amps with low powerratings, could drive speakers at such low impedences. Opening up the “hood ” of the amp gives you a strong visual indication of the ‘brute force’ method used to get an unflappable amp that could drive anything on the market then and today. D’Agostino’s assault on the highend poweramplifier market was very successful worldwide due to these first designs. After Levinson and Threshold, Krell established itself as a strong contender on the highend audio-market. Sound quality This range of first Krell designs redefined the meaning of bass-slam. The KSA-100 sounded much more powerful then it’s relatively modest rating of 100 Watts with acceptable levels of refinement in the middle and high regions of the frequency-spectrum. This stereo-amp is a alround workhouse that was often mated with tube preamplifiers from Audio-Research and Conrad Johnson. Not delicacy and transparancy as the best offerings from Levinson and Threshold but nevertheless highly recommend.

    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

  • 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

    Crown Reference 1

    Crown Reference 1 ships to you in 6/2017 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.
