    I have a 60’s Gibson Titan Medalist amp that has a fried power transformer. Part number is TF-135-P.
    The specs according to a schematic that I found online are...
    Primary 0-120
    Secondary HV 330-46-0-330
    Fil 3.15-0-3.15
    CT 660V
    The schematic is rather blurry and hand written, so it was pretty hard for me to read.
    My confusion is that when I contacted Heyboer Transformers, the specs they have for that transformer said
    Primary 0-120
    Secondary HV 380-55-0-380
    Fil 3.15-0-3.15
    CT 760

    So I don’t know if I want to trust the schematic or go with the higher specs from Heyboer!

    I don't know the specs for the transformer you are looking for, but you might give a call to the fine folks at Mercury Magnetics. They will probably know and if they don't have a replacement, they may be able to rewind the old power transformer to the original spec. It's worth a shot in giving them a call.
