This is excellent guys thank you so much! I have ordered brand new resistors for the amplifiers. This weekend i will attempt to test the capacitors, I think i will leave it at 15 ohms.

I also have an oscilloscope, I wanted to test the output power of the amplifier, from what I read I can't just put the leads on the output, with valve amps I need to put a load? Is this correct, forgive me I'm getting back into my hobby of electronics and testing.

Thanks for all the info and help! Frank if i get unsettled dealing with 400V and testing can I come see you?
