Model 20 Wiring
#10

I finally finished recapping the filter caps and had to scrape and eventually burn out some of the tar to get the 630v caps in the can. I probably didn't need to use 630v but since the originals were rated at 1200, which I thought was an overkill, I didn't think they'd pose much of a problem other than fit. The 1.5 uf was of course the largest but, I got all of them in, did some rewiring due to the old wires being brittle and green looking.

I replaced the two 71A output tubes and the detector tube and hooked up a 20 ga wire for the antenna but no ground. It pulled in quite a few station just sitting on the work bench and the only problem is a slight hum between where no stations are and a fairly loud crack when you turn it off. Other than that, I'm pleased with it. All filter and bypass capacitors were replaced as were all resistors. I had done most of that before. It's playing better than ever other than the above.

it certainly won't be metric! SAE threads were all that was known then. Take care, - GaryGarySP — 10:58 AM

Thankyou for the kind words sir. I double checked it with my component tester and it read 2.7 ohms at .02mH.Stormlord5500 — 08:14 AM
