I recently got my hands on an m11 that has seen better days. I am restoring it, but i am having trouble finding the specs for the transformers. Oh i forgot to mention the transformers from the amp have been missing for some time. Anyone that could give me any info i would greatly appreciate it. Thanks.

What are the following details to the output transformer:

Output tube configuration
Speaker impedance (probably a single 8-ohm speaker)
Spacing for the mounting bolts

Several amplifiers from several different manufacturers used the same low-wattage output transformers, so finding a replacement may be fairly easy.

The power transformer is more problematic, because there is a filament tap, a B+ tap to get bias voltage to the power tubes, and possibly others. But again, if you can figure all that out, the circuits were relatively straightforward and can usually be figured out.
