I purchased this Mono amp to modify into a Guitar amp, but it is just too nice...it is very very clean with zero rust, which is a surprise for its age.
It is stock from an organ (?) and has two prong power cable and no switch. I did add a fuse on hot wire and removed the Death cap. No other modifications were made.
I recently opened a thread to find schematic and link is below.

It is a Push Pull 6V6, with a 12AX7 driver and Phase Inverter and a 5Y3 rectifier.
I also noted a bit of arc flash in rectifier due to the somewhat large PS cap, so I was using a Octal Base fitted with with SS diodes as the rectifier with no issues.
All tube included.
Pics forthcoming
$120 + ship or pick up in west sub of Chicago?
