I recommend replacing both power transformers. The original ones have a 115V rated primary causing filament and B+ overvoltage at todays voltages, whereas the new replacements are rated 120V primary. Also, be ready to give the new PTs a lengthy break in period. After replacing mine I was struggling for a long period to try and find why the amps were hard sounding. After a couple of hundred hours they smoothed out and all is wonderful.
