Hello, I am noob audio engineer from South Korea. My father was audio engineer and professor in 70s.and now I got his heritage(I used the word 'heritage' because he is too old to continue making amp because he can barely see. He is healthy) I have his 6v6 pp amp and other tr amps. Especially the 6v6 pp amp was his last work as he retired as a engineer and professor.(look at the pic) It had wonderful sound. But it is too old, it keeps causing problems. I don't want anyone to fix my father's work. So I want to study audio on my own and fix it(it is still not working)and also make my own amp too. Now I am making 6aq5 se amp for study. But I need advice from anyone here, so I joined the forum
Welcome to the forum!
A power resistor bundled up with some electrolytic capacitors (as seen at the left side of the pic) is likely to damage the capacitors. They should probably all be replaced and then kept well separated from the power resistor.
Also, old solder lugs bolted to connectors or to the chassis may become corroded over time. They should probably all be checked for tightness.

Thank you I will fix it,if it is possible and also I saw loosed lugs I reattached it but still have distortion.
Hi aster peter99,
Nicely put together - except for the electrolytic capacitors tied to the power resistor. Previously noted.
I'm glad you are restoring your father's work. Very fitting. His hand, followed by your hand.
That amplifier should be fully repairable, and last for years to come. Also, I often find riveted lugs that have become intermittent or resistive these days. Drill out rivets and use machine screw hardware plus toothed washers to make good contact.
