Hey Jonathan, you and I seem to be in the same boat. I found that if I worried too much about trying to verify my problem through resistance readings then I was driving myself crazy. I don't know if you have read my similar thread about problems on my TC-127 but my conclusion was that if I was getting smoke from my transformer with everything on the secondary side disconnected then I should start looking for a new transformer. Its pretty cut and dry. With me I just did not want to find out that the 57 year old transformer was my problem.
As I said earlier in this thread, I think that the power supply was the weak point on these early RCA sets. My smoking transformer may not be an original RCA part to begin with. It bears a 970972-1-3/138012 stamping where as my older 8T-243 has a painted on RCA logo and part #. That transformer works even after handling the load of DC filters that were gone enough to flash open the 5u4 filament. So maybe my bad trans has already been replaced through the years. Who knows?
The good news is I found a Merit replacement and should receive it next week. Wish me luck!!
