It must be the way they rate than theta. Audio spec must be more forgiving than something that has higher duty cycle.
Well, I completed the restore and it looks and sounds great. All of the coupling caps I replaced were really leaking and way out of spec, one was leaking 2amps at 400v and not going down, most increased current leakage during testing which should not be the case. A couple of the bypass caps would not even register as caps with my Sencore and my cheap tester. I also replaced a few resistors that were out of spec. I did use cans, sorry, I like to keep original as I can and they fit really nice and tested excellent. I mostly used orange drops for everything else. Yes, I even took out the time to unsolder pins to add the new components, I was going to do the old wrap around but I kinda knew I wouldn't before I started.
The amp sounds great and it is real quiet, no hum what so ever. I removed the cap on the primary side of the power transformer. The schematic was wrong, this cap is across the lines not line to ground. So far I found 3 errors with this schematic, yes the one I have which is same that is stuck to the bottom of the amp. The cap that was on the secondary Tube filament to ground was needed so I replaced it with a .1uf 400v orange drop. With this removed, no audio, just hum yet was sensitive to the input and the tubes were lite. Did not trouble shoot to find out why but looking at the circuit with this cap at the center of the transformer filament output, I see a ground reference. If I am wrong, please correct me. The cap that was in there was a .1uf 400v Stomberg paper/wax cap which tested good as did the .1uf Stromberg paper/wax cap on the primary side. These were the only caps I took out that actually tested good. I did install a 3 wire cord also.
By the way these orange drops tested with ZERO leakage at 400v with my Sencore. I just love those orange drops.
