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

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

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.
