I have a vintage '50s Fender Pro that I bought off a lovely little old lady in San Francisco a few years. She also sold me a beautiful 1966 Gibson ES-175D that I cherish. Yes, it really was a little old lady--she had taught music for 40 years, including private guitar lessons for 25.
I have posted some photos below, and I was hoping that someone smart here could tell me more about this amp. . .
The tube sheet says it is a 5C5 (C3), but the last three 6SC7 tubes are crossed out and replaced with 12AX7, in the same ballpoint pen as the serial number.
The power tubes are Sylvanias and the 12AX7 tubes are all GE. The tube cover for the last tube on the right is an obvious later replacement.
The speaker is a Jensen C15N. I have no idea if it is original. I thought this model didn't come out until the '60s, but I can't find anything online that says so definitively.
The power cable was changed to a 3-prong at some point a long time ago, the old lady told me. She thought something else might have been done to the amp, but she couldn't remember. It was serviced every 5 years or so.
Finally, the little old lady thought that this amp was a 1954 model. Her father had bought it new.
Thanks in advance for any wisdom y'all can offer on this amp--I am truly appreciative!
