I am working on a vintage 1966 Kustom amplifier ("Frankenstein" style) and need any support documentation anyone may have available.
I have been asked by a friend to see if I could fix the unit. This amp has a special nostalgic value as the owner worked at Kustom as the QC operator doing final test with his guitar. He obtained this unit while working there.
Any help with schematics or hand written diagrams would be appreciated.
