The amplifier is designed around the ECL82 tube, which includes both a triode and a pentode in one package. The ECL82 is practically an amplifier in a tube: it was designed for low-cost electronics like record players that needed to be as simple as possible. The triode in the ECL82 is used as a pre-amplifier for the incoming signal. The pentode is controlled with the pre-amplified signal and acts as a power amplifier.

Low-Voltage Tube Amp Is Great For Beginners


The M3 Pre-Amplifier Family. This involved redesigning the output transformers to allow us using newly developed HiB materials, a revised line stage where we changed the first stage valve from the standard WB to an ECC82 type many versions available here, for example 12AU7, , a, w, , E82CC, CV an many others to reduce the sound of repeating the same valve and circuit coupling in subsequent stages and modified the second stage line valve to either a , or depending on the balance we felt appropriate.

The first step in this direction is presented in the M5, followed by the M6 and finally the M8 pre-amplifier, making up what we call the M3-pre-amplifier family all of whom share the same circuit topology across the range. Above the M3-M8 family you will find a couple of super quality pre-amplifiers the M9Phono and M10Line phono version is still in development, in these pre-amplifiers we will take the power supply design, valve choice, materials, circuits and component quality to new heights with a price to match, as anyone who has heard them can testify to!

The above is a demonstration of how our philosophy of developing the best possible circuit and power supply provides a great platform for creating substantial and in many cases almost shocking improvements in sound quality by raising the component and material quality to ever higher levels.

Consider how many other audio manufacturers master the understanding of component and material quality to this degree. This comparison is easily done and is also an instant measure of the seriousness of any audio manufacturer. Just check if their specification includes anything like the above array of truly specialised audio parts and materials displayed above and then ask your self.

I credit most of you with the intelligence to answer that question, so answers on a postcard please! The best answers will be credited with a meter of silver interconnect provided I can use it for my own devious ends! Please consider the degree to which our very large and in depth stock of exotic parts and valves, represents an investment that requires not just money, but also a combination of faith in the pursuit of absolute sonic quality combined with a very considerable and highly developed technological know how and a very sophisticated aesthetic.

Cost pressures prevail everywhere and elsewhere in the specialist audio industry, as in most other branches of consumer products, the relentless pursuit of ever-cheaper products to provide higher profits through lower and lower production costs continues unabated. Add to this the fact that a pound spent on marketing and promotion seems to have proven to be much more effective at selling a product than a pound invested in better quality parts or better design.

Remember in this context that the money can only be spent once. Bear that in mind next time you pick up a glossy brochure, respond to a designer advert or admire a stunning finish or visual design. Time favours performance quality rather than fashion, which is devalued quickly after the first admiring glance, which is why the best old audio products still command premium prices.

But one which should be learnt from perhaps? Over the past 30 years this process has been repeated so many times that it takes real ingenuity, effort, resolve and considerable historical knowledge and overview to reverse, which is something that most members of our convenience oriented culture are not prepared to invest any time in, so it is left to someone as fanatical about the beauty of really well performed and reproduced music as my team and myself to pursue this with uncompromising commitment and vigour!

The Evolution Line One is full tube stereo line preamplifier in the Evolution series. It came as a logical extension of the Elegance Evolution power amplifier. Consequently, we were challenged with a difficult task of meeting high quality of the existing Evolution products. This product, as well as all the previous ones, is built following the principle of using minimum of active parts with the top quality passives. After the long development and multitude of circuit variations The Evolution Line One was born. Previous experience has shown that only a no-compromise design is worth the effort and we followed that philosophy throughout this work.

This calculator allows you to trace the anode characteristics graph, and to compute and tune loadline and operating point of various vacuum tubes. Did you buy my book? Remember to leave a review on amazon! The underlying model and equations, for tracing anode characteristics curves, are those discussed by Norman Koren, in his web site. Very useful calculators!

It has a pentode plate dissipation rating of 7 Watts with convection cooling. A single 6BM8 may be used as an economical low power mono block amplifier or a pair of 6BM8 's, in ultralinear configuration are an excellent choice for more power. Close manufacturing spec ification tolerances and improved processing provide enhanced reliabilityand superior sonic performance. The high sensitivity of Svetlana 6BM8 's is an economical methodto achieve high quality sound with a minimum of components. General CharacteristicsElectricalHeater: Min. Voltage AC or DC 5. Seated height71 mm 2.

ECL82/PCL82 is an excellent example of this class, with a useful maximum output of You could use exactly the same circuit with PCL

BZXC3V0, : 9. This is a variable gain type with 20dB dynamic range. It very low distortion and Pacp is less than at 17dBm output power ,and enable low voltage and high efficiency operation. Small Plastic mold Package are adopted.

High Voltage rectifier circuit use Vishay 1N as bridge for full- wave rectifier. A low dropout regulator LM is used to supply the filament. As all resistors and capacitors are low-noise with good channel matching, the sound quality should have low distortion. Shuguang 12AU7 x3. PCB thickness: 2. Separation PCB design of ground and supply voltage between main circuit block and power supply unit.

Cheaptubeaudio has had a long history of advocating reasonably priced but excellent tube gears, particularly Singled-Ended Triodes. This Blog however covers a lot more than SET, and is not exclusively tube-related.

    In my opinion, you are making a mistake. I can defend my position. Email me at PM, we'll talk.
