Craftsman RC200 resto
#18

Had a chance to mess some more with this TV and did make some advances, but not there yet. My B+ voltages were quite a bit higher than specified, so I moved the line voltage selector (at the top pf the last pic) over to Hi. Well, evidently this means B+ and not line, or something is backwards, so I moved to the Lo and that put my B+ about 10v over what is on the diagram, and probably is right on if I used my old 1000ohm meter. 

Well, I had no video off the tuner but good sound. So I started making some checks in the IF section, since I can get video from an injected signal at the detector. I found an open plate resistor on my 3rd video IF, no plate voltage. Ah-Ha! So I replaced that and got  my plate voltage back - still no picture. Just a blank raster. I started to flip the channels for no good reason and when I hit 10, I had snow on the screen! Well, if I can get snow, this means the IF stages are now working, at least in part. So I fired up my modulator and set it on ch 10 and was able to tune in a picture, but no sound! Ugh! Gotta love these split carrier sets! So, I either get sound with no picture or a picture with no sound, which has me at the tuner now. 

I cant use my tuner sub box because this IF uses 22mc and my tuner uses the modern 45mc. So, I am stuck waiting on a capacitor for my 1077 from AES that has been across my state at least 2x and may finally make it down to my mailbox this week. I can tune it to the correct frequency and make some tests. .
