My ’63 ser# BP05546 came original with the lower B+ 125P19A PT. I understand a few twins were fitted with 7591’s used that PT. Anything is possible in Fenderland. I subbed a 125P7A clone while the original was rewound/reverse engineered but the sound was too clean & stiff for me. When the 125P19A came back so did the incredible tone/feel. IHOP a lower B+ with 120+ AC probably mimics the factory spec PT with early 60’s 110V.

Привет! A stock 63 Bassman will have smooth blond tolex and a wheat grill, but don t get too hung up on the cosmetics. Over the past few decades, many of them have been retolexed or had different cloth installed. These are easy things to replace unless you absolutely need a completely original amp and cab.

I have a ’64 smooth blonde tolex head and cab. Tube Chart Date NF (June 1964). Chassis is ink stamped inside with TC2364 (June ’64), Filter cap board stamped FA2064 (May ’64). Tube Chart on the 6G6-B label shows 6L6 power tubes, not 5881. Also the original cab contains a pair of Utah 12″ stamped 328418.
