Thermaltrak amplifier tubes

A patent was granted that same year for the Unity Coupled circuit and transformer. A week after the MC's arrival I saw for myself, on a guided tour of the plant, how it all comes together. What are you? The solid-state MC power amplifier replaces the MC and is now the most powerful stereo amplifier McIntosh offers, with a specified continuous power output of Wpc into 2, 4, or 8 ohms, and peak output current of 75 amperes per channel.

So what do the forurm members think? As in Kessler's previous top-of-the-line designs, these amplifiers are fully balanced, differential amps, but unlike his earlier balanced designs which were essentially balanced bridged amplifiers, the series uses only a single input stage with dual-differential output stages.

The design uses current feedback instead of the more common voltage feedback. The reason: current feedback amplifiers are faster with virtually unlimited slew rate and are better able to reproduce today's best music and film sound.

Kessler used Thermaltrak output devices for the series. Unlike traditional designs where external diodes or transistors attached to the heat sinks track the amplifiers operating conditions and use the details to adjust bias, Thermaltrak devices have the temperature sensing device in the same package as the output transistor. The results: bias is optimized in real-time. The series use dual DC servos to track and maintain DC offset. The result: DC in the amplifier's output is reduced to insignificant levels.

These amplifiers use a revised PCB layout. They are still modular with the complete amplifier including the power supply parts on a single card, but now the AC components are on one edge of the board and away from the signal input.

The result: improved signal-to-noise performance. All of the amplifiers in the series use dual toroidal transformers, dual power switches and dual line cords. The results: the AT is now a complete dual-mono design and the amplifiers with many channels, as in the 7-channel AT, can be hooked-up to two independent 20 amp circuits for greater sustained output power than is possible from a single AC circuit. Signal-to-noise ratio is typically dB referenced to full output so each amplifier in the series is capable of playing back the full dynamic range available on today's lossless recordings.

Specs are nice but seldom tell you how it will sound with a given speaker.

I have 3. Best sound I have ever heard in my house. Do not like ss except maybe the Pass amps and the oddeseys Alan.

The specs do tell you something and i would be most concerned about how much the current limits going from ohm , apparently they didn't invest much into the PSU for their thermal tracking output devices.. The listing of all the specs sounds to me like manufacturer hype.

Some of the features are nice but probably have no real advantage - for example how many users are going to have two independent 20A circuits available. The spec that I would be most interested in - the ability to double down, which by the way is what Magnepan recommends - is sorely absent.

Of course this may not matter if you go to active biamping. As the two other previous posters have said, "How does the amp sound? You really need to be able to audition it before purchase.

If it were me, I would be looking at the Sanders Magtech for about the same money as it has a proven record with Magnepans. They could have adjusted their rated the output power to wpc into 8 and into 4 as some manufacturers do, so they would then appear to double down. Yes but that would be advertised not factual , can you name an amp that claims to double down and measures not Most if not all manufacturers tend to overstate the power since relatively fewer customers understand the implications of doubling down and there are plenty of buyers who think of amplifiers like muscle cars.

Davey Audiophile Posts: Joined: September 26, I suggest to read up on Morris Kessler. The ATI amplifiers are superior designs Many design features and they build their own multi-secondary transformers in-house. You won't find anything better in any amplifier anywhere. It's going to take a lot of 'Muscle', American or otherwise to move them around; 88 to lbs.

No matter how it performs it's still a killer of an amp! A buddy of mine uses them on in a quad amp mode on his linkwitz speaker great sound Thanx. Current limiting almost never a problem However some amplifier do have a switch that select 4 ohm operation that in many cases reduces the rail voltages of the power amp at lower impedance to inexpensively "protect" the power amp. Other amp will change the current limiting cuits of the power amp with the impedance select switch.

The power supply needs to be able to supply the peak current only for a moment or so. And yes - sometime the instantaneous current need to be supplied when the voltage is lower than peak. And for fun you could also spec it for a challenging degree inductive phase load as well.

I firmly believe everyone connected to the audio business or who is a HiFi hobbyist has personal biases as they relate to amps, speakers, DACs, turntables or cartridge design. I most assuredly am not immune to these biases. However, my choice of Arcam comes down to what works well with my primary speakers. Many years ago, I had them attached to a McIntosh watt per channel stereo power amp which was an excellent power amp but they sucked every watt and bit of current from the design and still wanted more. I have used dozens of both tube and solid-state amps on my speakers and come to the realization that high current solid-state trumps ethereal tube musicality. I have considered changing my primary speakers but again it comes down to personal taste. The reason for this confession is to make you the reader aware of my personal biases upfront. The purpose of this article is to talk about amplifiers. I will be commenting on both solid state and tube designs, plus the most common variations of each.

Designing Audio Power Amplifiers begins with power amplifier design basics that a novice can understand and moves all the way through to in-depth design techniques for very sophisticated audiophiles and professional audio power amplifiers. This book is the single best source of knowledge for anyone who wishes to design audio power amplifiers. It also provides a detailed introduction to nearly all aspects of analog circuit design, making it an effective educational text. He is an equal-opportunity designer to this day, having built amplifiers with vacuum tubes, bipolar transistors and MOSFETs.

We are currently experiencing an increased volume of online orders, along with delays and general congestion within our freight and logistic networks. Unfortunately, this is resulting in delays getting some of your orders delivered to you on time.

How do I build My guess is that for every tube fancier who seeks to understand how tube circuits work, there are at least one hundred other tube aficionados who just want tube gear, preferably without the conceptual overhead. Imagine if one had to understand how a microwave oven worked before being able to buy one. But at the same time, the glory days of great kits from Heathkit and Dynaco are long past. What we are left with is a much more demanding task, building tube projects that require much more from the builder, as he must construct his own chassis, power supply, PCBs, wiring harness,… In addition, he must know how to solder and wire a project; and should the project not work, he must be able to do his own troubleshooting and repair.

The Sanders ESL amp Mk II is the latest in a long series of upgrades to improve this unique amplifier that is designed to drive the most difficult of all speaker loads — electrostatic loudspeakers ESLs. Since the most common type of speakers are the magnetic speaker types, most amplifier manufacturers do not design their amplifiers for electrostatic speakers. As a result, most have problems driving these difficult speakers.
