Plate voltages for UV-200 tubes
#10

Well here's an update on what I found tonight. The audio output section is working fine, however I'm not getting a signal through the 2R section and back (RF section). When I touch the plate of the UX-201 tube in the 2R section I get no buzz only very faint change in static. The 3 coils all check out fine, both primary & secondary for continuity. The antenna connections check fine for continuity (but I get no change in sound when I touch the antenna connection lug with the set on). I'm thinking it has something to do with the tuning capacitors themselves. I know that the 1st tuning capacitor had 'fins' touching and I tried adjusting it a bit. More work tomorrow I guess. Funny how quickly 3 hours can pass when you're working in the basement on a radio Icon_smile
