My set has the 27ZP4 picture tube, which tested much like this one did, but at least it lights and I have a full raster. The problem I'm currently having is that I have no audio nor video, so I need to try to troubleshoot that. Sams has schematics for the C36 series chassis, but none of them are exact. I hope I can get mine going since I have had the rest of this thing apart as far as I can get it, including the cabinet. I found it in an abandoned house in Detroit that was being torn down. It had a half inch of cigarette scum all over it. Mine has remote control and the whole shot. Top of the line model for 1962. Mine does not have the UHF option.

From what I can see, the ones set up for audio output via a separate Stereo amp , tap off sound at the plate of V7 before the 6GC5 audio output tube, but still have the 6GC5 in there as a voltage divider for the 120v source, which is critical for the video and audio IF sections, and the tuner, so if there was no 120v, you would have raster only
