Well, upon further investigation, I found that there are two chokes in a large compartment that houses the PT, #80 rect., and one big honkin mother of a capacitor. The lower choke had about 150vdc in and about 139vdc out. The top choke had 12vdc in and nothin out

I'm thinkin open choke, but I don't want to go jumpin stuff out and screw something up. I'd hate to think that a radio could survive since 1928, and meet up with me and go out in a blaze of glory.

Surely there's some old-timers around here that used to have to get one of these goin to listen to Roosevelt
