Progress report.
After replacing all the paper caps the set still doesn't work much better than it did before.
I get a weak raster but I also get a high pitched squealing noise through the speaker, it seems to be the Horizontal Oscillations getting into the audio, the volume control has no effect.
I also don't seem to be able to get the Horizontal on frequency, though it's hard to tell with all the noise, however if I go one way it starts squealing and the HV quits, go the other way and it fades away. The 7AU7 tests so-so on one section but I doubt it would cause a problem, I haven't tested any other tubes except the Damper and Horiz Output (oddball 25DN6?)
I tried jumping all the Electrolytics to no effect, I couldn't jump them all at once however and that doesn't eliminate the possibility of a short between sections.
I also found I don't have or at least can't find the Sams for this set so I'm working blind here.
Would anyone have a copy of a Sams 348-10 they could scan for me?
Just the schematic part would be OK for the time being, I could use all of it eventually though.
Not positive about that Sams number either, the model number on this set is blank but a 2004F is the most likely suspect (the F suffix is most likely just the color Fawn?)
I appreciate the help!
