Dave's 1962 6G7-A Bandmaster In Progress Page
03/14/04
Dave emailed me a while back and said he had a 1962 Blonde Bandmaster that was real hacked up. Dave sent me some pictures, "ugly" I said, "but sure, I'll take it on, I like a good challenge." Well, that was then and this is now and now that I've started working on the amp, I'm placing a $1000 Bounty Award for the capture of the hack who completely butchered this amp.
People, please pick on a mid '70s Bassman for your experiments. Better yet, don't start with any old amp, build your own buzz saw with one of the many now available blank chassis. Argh!
Anyway, I'm going to have to completely rebuild this amp. Almost as though I was building an amp from scratch. Heck, building an amp from scratch would be easier.
Initial Condition
Rusty power tranny. Original, but hacked, power supply caps.
Hacked up fiber board, wiring and even a few new holes.
Why would one try to convert a Blonde era amp to a Blackface AB763? Just by a
dang Blackface amp!
Restoration Progress
Chassis stripped and ready for cleaning. Cleaned results.
Cleaned rear plate and new on/off switches. Cleaned and pounded straight
faceplate.
New caps. Stripped chassis guts.
Stripped fiber board. Stuffed fiber board with new and correct parts.
All correct pots in place and wire threading in progress.
Completed wiring.
In test.
