Hi.
Nice write up and a good job well done.
I'm 90% through a Bassman 50 Silverface from the early 70's. It too is whisper quiet, the Mallory electrolytic caps being the next job.
This amp though was mighty rough being left in a wet garage for nearly 20 years, the paper composition tag boards were in an awful state. The rectifier board was binned and a new one made out of tag board, same size and far more professional than Fenders original, the smoothing section was also the same and it got the same treatment. Fortunately the main tag board responded to a long soak in isopropyl alcohol and 24 hours on an oil filled radiator.
All 6 controls were seized so needed replacement, just awaiting on the low voltage caps to come then job done.

Hi Dick
Bear in mind that if you go for a US model it will have a 110v transformer. The most cost effective option is to replace this with a UK mains tranformer - this does escalate the cost considerably.

Hi Trevor,
You are making me very jealous indeed. If its been wet garage could your problem be the output transformer??

Hi.
The Amp is now working well, just some cosmetic items to attend to.

Hi Alan
No not this time thanks goodness.
Unfortunately as I thought I was winding down towards potential retirement, I was seconded to a job in Sellafield for about 7 months and my return to London was promoted to Associate H&S Director. I seem to be busier than ever!!
