I just got some old tube amps that are in disrepair. I am in the planning stages of rebuilding and/or redesigning them. The models I have are:
Masco: MA-25N and MA-8N
Executone: PB-325
I have a general idea of what I'd like to do with them. I think I will restore the MA-8N to use as a nice little guitar/mic/whatever amp, mono. I will also restore and upgrade the PB-325 to probably use as a sub amp, mono. Does anyone know of schematics for the MA-8N? I will scan and post the PB-325 schematics.
The MA-25N I have bigger plans for however. I want to gut it and turn it into a nice hifi stereo amp. It appears to have a nice power transformer that i can use. After cleaning up the metal case and painting, it should be nice. So the deal is, now I am entertaining all sorts of hifi push pull circuits.
