Thanks Sluckey. I couldn't understand how I'd replace 4 with 2 as each diode seems to be an essential link in the circuit. Ok I'll do the power cord and caps, clean up as much as I can - good layer of nicotine on everything and it's like a shellac! -then power up and see what I got. PO used the amp recently so I don't think there are any major issues besides lack of ground. Cap replacement seems to be just good practice but I stand to be corrected on that too.
cheers, hawk
electrolytic capacitors are like brake pads, they wear out over time and if you let them go completely, some bad things can happen. It's best to replace them every 15-20 years or per the manuf recommendation...
Thanks for all the help folks. My first tube amp job was a success! 4x new caps, 3-prong plug, and all new tubes. Came with some Japanese Philips 6CA7's and some mullard 12ax7's but they were spent.
