  • Linn AV 5105 Stereo Power Amplifier

    Linn AV 5105 Stereo Power Amplifier

    Linn AV 5105 Stereo Power Amplifier, tested 5/18 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

  • 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

    PS Audio Stellar M700 mono amplifier one NEW in stock in silver

    PS Audio Stellar M700 mono amp in silver, full factory warranty The Stellar M700 mono amplifiers are a massively powerful engine capable of effortlessly driving demanding loudspeaker loads to concert levels. Stellar’s best. A pair of these placed on any loudspeaker brings forth the lush, rich and soul-satisfying power of two completely independent power blocks with headroom to spare. One listen to a hugely loud and complex musical passage effortlessly rendered by the M700 pair and you’ll know you made the right choice. Rated at 350 Watts into 8Ω and 700 Watts into 4Ω, the M700 combines the best of two worlds: ultra linear, high-current, Class D technology for the output stage; a discrete, Class A MOSFET based Analog Cell for the all-important input stage. The M700’s rich, warm, and engaging sonic character comes from the Analog Cell. Its powerful, authoritative control over the loudspeaker stems from its high current, ultra-low impedance Class D output stage. Stellar’s design imperative was to produce a truly musical sounding power amplifier that proudly competed with any amplifier under $5,000. Its designer, PS Audio engineer Darren Myers, took the challenge and set to work on a new concept—a hybrid that would combine the best of today’s technology with time-honored techniques leveraging PS Audio’s forty plus years of experience. The results are extraordinarily musical. Even from the earliest prototype we knew the Stellar power amplifier series was going to be something special. Stellar amplifiers never draw attention to themselves, a rare quality in amplifiers of any price. After hundreds of hours of tuning, voicing, and perfectionist tweaking, we were confident the ends justified the means. Audition the Stellar M700 pair and you’ll appreciate Myer’s dedication to musical truth without compromise. Learn More

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.

    PA1230R Integrated Amplifier At a time when many manufacturers are using microprocessor technology to bury functions below several software layers so you need to have an owners’ manual close at hand if you want to access them, T+A has delivered an amplifier where each function has its own control, properly and clearly labelled, on the front panel. This necessarily means there are quite a few knobs and buttons, but rarely has an amplifier been so easy to use. This is especially the case because the PA1230R is one of the very few amplifiers available that allows you to adjust bass and treble individually for the left and right channels. Learn More

    Mark Levinson 33 set of monoblock amplifiers

    King of the HIll! one owner These were top of the line for Mark Levinson and will drive any speaker. These are one owner 110V units. The Nº33 Reference Mono Power Amplifier uniquely combines extraordinary power delivery with effortless control and unparalleled refinement. Rated at 2,400W continuous into 1-ohm loads, it is the most powerful high-end amplifier in the world. The Nº33 incorporates two 2.45 kVA low noise toroidal transformers in a fully balanced power supply. In this design, there is a separate power supply (each with its own power transformer) for both the inverting and non-inverting halves of the amplifier. Twelve 39,000 μF low ESR capacitors are used in each amplifier. The power supply of each Nº33 provides almost 1⁄2 a Farad of capacitance and 1200 Joules of energy storage. Heavy oxygen-free copper bus bars enhance the efficiency of power distribution within the amplifier and eliminate variances introduced by the wiring harnesses, etc. more commonly found even in high performance amplifiers. High frequency power supply bypass is accomplished on individual PC boards by a total of 56 components of several film types. The resulting uniformly low power supply impedance seen by the various circuits within the Nº33 lays the foundation for both the massive power and the extraordinary finesse that characterizes this amplifier Learn More

    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

    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.
