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!
