'66 Bandmaster w/Tube Rectifier mod, Replacement Transformer

Postby Slrstcs on Wed Jan 25, 2017 2:49 am

I bought a used '66 blackface Bandmaster from bongo center online- was really excited as the 'vintage' aficionado insisted it was basically factory stock, all original.

The amp arrived with a 5U4 rectifier tube- so clearly modded, and the transformer doesn't look original to the amp!

I need to get some pictures hosted somewhere- would really appreciate any insights you guys have as to what else may have been done to the circuit.

Thanks and all my best-

You may ask to the seller some money back because it is not original, value drop.

Seller do not post some pictures before you bought it ? You buy it with no picture ?

We will have to see some pictures. Obviously it is not original. In the meantime, list all transformer codes so that we can see what you have. Any refund due would depend on how much you paid for it.

Blackface Bandmaster heads seem to run $500-700... maybe a $100 more than a clean silverface. There's not a lot of shift for replacement parts on these. Not that I wouldn't ask.

It sounds like those parts have been changed, however I own a '61 Super that has a stock solid state rectifier instead of a tube as they normally have. I've never been able to document it, but it may have once belonged to Barney Kessel - there is a Dymo label on the back the says "Kessel". The power transformer is the code for a Bandmaster which would have used a solid state rectifier.

JeffH that is a very cool amp! I have a clean '63 Pro Amp with a tube rectifier that is as original as it can be. No idea who it was built for, but Fender did do custom work for established musicians until the mid 60s.

Sirstcs can you post pics of the circuit, transformers and tube sockets?

Some Brown Pro Amps was sent back to the factory to get the solidstaterectifier replaced with a tube. I've seen several pics of different Pro Amps with tuberectifier so it's not that rare. My have a 125P5B TP. Date is LL/Dec 1962 and it have been back at the factory week 25 1963 and it was probably then it got the 125P5B PT.
