    Newcomb D-10 conversion from HiFi Mono to guitar amp?

    I have a Newcomb D-10 that I want to mod into a guitar, bass, and/or harp amp.
    Does anyone have a schematic? The schematic on the bottom panel is damaged.

    Also, any recommendations regarding things I'll need to change (aside from the obvious replacement of caps) in order to make a good instrument amp out of it?

    It uses a 12AX7, a 6SC7, a 6AX5GT, and two 6v6GTs.

    Is this a viable conversion?
    It has 6 different inputs, and it has both an 8 and 16 ohm output.

    If you post to the antique radio forum, someone there might have a schematic. It appears in Sams photofact, i think 1956 is before the copyright fiasco so it should be able to be posted.

    Honestly.. I always say this. But I would just use the iron and the chassis... MAYBE some pots if they arenít shot. New ceramic tube sockets are $2 apiece. A new turret board and all new components wonít break the bank either. Could save you hours chasing wierd problems in the future. You can also cut some sheet metal for a new control front with the number of pots that you want in the place order you want.
