Old tubes and chassis out.
Dirty pots soaking in naphtha.
After the pots were installed(and lubricated) I found these two components(cap and bridge rectifier) and a wire loose. I read up a little and it seems like a common issue with these amps.
Those joints were cleaned and flowed with new solder. Next I installed a couple of resistors to measure cathode current for biasing.
Done(after setting the bias)! I had a picture of the new tubes glowing but it seems I erased it before uploading it to my computer. D’oh!
Thank you so much for fixing all that you did, my amp sounds absolutely amazing now! All the noise problems I was having are gone too! thanks so much for everything!
