  • 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

    Jeff Rowland Model 501 pair The Model 501 is a 500-watt monaural amplifier enclosed in a chassis milled from a solid block of aircraft-grade aluminum. We believe that this approach to isolation contributes significantly to the amplifier’s ability to isolate delicate audio circuitry from external vibrations and electromagnetic fields. The Model 501 incorporates advanced digital output devices that, when driven precisely, provide an extremely accurate transfer of energy from amplifier input to output. Midrange sonics are rendered in smooth and linear fashion, while bass is tight and defined. Treble frequencies are extended and refined. Its incredible power reserves allow it to accurately reproduce the mightiest orchestral crescendos while maintaining the delicate filigree of quiet musical passages. The 501 enclosure never heats up much beyond body temperature and can be placed virtually anywhere within the listening environment. The remarkable size and weight of the 501 allows for placement rarely noted in previous high-power amplifiers. The 501 is designed to successfully drive the great majority of modern loudspeakers available today.

    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.

  • Linn LK85 (2 available, price is for each)

    Linn LK85 (2 available, price is for each)

    Linn LK85 tested 5/18 This model of Stereo Power Amplifier operates at 85W per channel up to 4 Ohms. The Linn amplifier is fully upgradeable, so users can update it when other components of their stereo systems are upgraded. There are four sets of speaker wiring on the Linn LK85, which makes bi-cabling convenient to put in place. The Linn amplifier is designed to conserve energy by going into sleep mode after 10 minutes of inactivity. This feature also preserves the circuitry, which can become damaged from frequently turning it on and off. The Stereo Power Amplifier is all black and is often referred to as the Black Box. There are no frills, and the basic look of the Linn LK85 allows it to go along with many other components of the stereo system without looking out of place. Key Features RMS Power at 4 Ohms x2 85 W RMS Power at 8 Ohms 62 W 115V Learn More

  • Hafler DH220

    Hafler DH220

    Hafler DH220, only one left for sale The DH-220 circuit is a refinement of the DH-200 design, a Hafler landmark which has achieved worldwide recognition, and has elicited glowing reviews since its 1979 introduction. As in the DH-110 preamplifier, particular attention has been paid to component quality, using polypropylene or film capacitors wherever feasible, for example, for superior sound. Combining the latest power MOSFET technology with uniquely simple and effective circuit topology reduces distortion of all types, and at all power levels, over the full audio frequency spectrum, to the vanishing point. Specifications Power output: 115 watts per channel into 8Ω (stereo) Frequency response: 6Hz to 60kHz Total harmonic distortion: 0.02% Damping factor: 60 Input sensitivity: 1.55V Signal to noise ratio: 100dB Semiconductors: 26 x transistors, 8 x MOSfet, 29 x diodes, 4 x zener diodes, 1 x diode bridge Dimensions: 5-1/8 x 16 x 10-1/2 inches Weight: 26lbs Learn More
