• WARNING: Tube/Valve amplifiers use potentially LETHAL HIGH VOLTAGES.
    Building, troubleshooting and testing of these amplifiers should only be
    performed by someone who is thoroughly familiar with
    the safety precautions around high voltages.

Just got done replacing all the electrolytics and diodes. What a great sounding little amp inspite of having .01 ceramic disc coupling caps. Has anyone replaced these caps? What cap did you use? Any impressions on the magnetic phono stage?

Ceramic caps are not very good, you are better to use mica, film or paper caps ... With a higher working voltage than the DC supply of course ... The best ones are "paper in oil" but they are expensive. 🙂
