Default Assembling the tube amplifier 6Ж4 - 6П3С.

Good afternoon! I made this tube amplifier for two years. Lamps 6Ж4 and 6П3С. In North America, these lamps are called 6AC7 and 6L6.

Here is the scheme

Since, in High End Audio, the conversation about money is considered nonsense and inappropriate, while I postponed this topic.

OK, 3 6AC7s for small signal and PP 6L6 finals. Do you have some measurements?

Obviously, a lot of work has gone into the project. Карашо!

Here the results of measurements made on the stand:

In the final assembly, measurements are not made. If you lean your ear against the acoustic systems, there is no noise. Tried variants of heating by an alternating current and a constant current of a difference is not present.

Would you mind terribly using our server to host pictures and test results? Most of the links do not render correctly due to character sets for Cyrillic not being installed in the browser and the links will eventually break making the thread useless to future readers.
