1949 RCA 8TR29 restoration

Yes a method of video injection would be ideal. In my introduction, I mentioned a lot of test equipment got auctioned off when our shop closed in 2000. We had a B&K Video Analyst which could inject IF or video signal. It had a kinescope tube inside with changeable video pattern mylar sheets including the classic Indian Head pattern. Damn I wish I still had that !!

Thanks for the tips guys. I checked continuity with the peaking coils and didn't find any open. I checked all of those 6AG5 tubes already and all tested good. I'll check those mica caps and check resistors around those tubes next.

I had a 1076, and keep a 1077...IMO any collector planning to do more than 5 restos should have one. They can localize so many troubles in so many circuits they are worth the time they save.

I have a BK 1075,1076 and 1077, but haven't used them much. I probably need to pull the 1077 out and learn how to use it on this set. I haven't used my capacitor tester much either, but I will try using it in the mica caps.
