It needed a bunch of wax-paper capacitors replaced so it could be used without damaging tubes. Came right up, sounds great for the age, no silver-mica disease. Nothing much on these days, but it makes the room nice and warm.

Had to replace the power cord as well, someone did so in the past but just used an extension cord. I used a proper thin insulation type cord, but with a polarized plug.

What's interesting is the chassis isn't hot on these. I thought it was, but even the schematic doesn't show hot. Line is returned to power ground, chassis is separate with a 0.05uF capacitor and 470k resistor.

I polarized it so neutral is returned to power ground instead of hot.

The SAMS for this one, 190-4, shows Run 2 but they're pretty much the same.
