I've been working on measuring and replacing out-of-spec resistors and all the paper capacitors. I found that the vertical blocking oscillator transformer secondary is open. I melted it out of its tar hoping to find a simple loose connection. No such luck, the open is deep inside somewhere. I was able to find a replacement from oldradioparts.com. Here is a picture of the old and NOS part. It has a -2 where the original has a -1, but its resistance measurements match the Sams. I also have found that some of my sets resistor values match the Sams values where they differ from the RCA schematic values. And also some in my set differ from both schematics. Here is a picture of the HO screen resistor which Sams and RCA (R269) list as 11K but my set has a 10K. Its soldering looked original, but I could be wrong. I guess they are production run changes. Is it best to start with my sets original values and see if I need to change from there?
I have also found all but one of my sets white peaking coils are open. I got some replacements from oldradioparts.com but had to get some from digikey. Can modern coils of the same inductance be used as peaking coils? I think the old ones as Pi-wound, no clue on the modern ones.
