The underside of the chassis looks very original, except for signs of the tuner having been removed before. And the ANT lettering on the lead-in terminal strip is upside down if it had been screwed to the cabinet, which it was not. The 1B3 HV rectifier was gassy, but most of the other tubes were in pretty good shape. I ran the 10BP4 CRT on the CR-70 at 8V for a few hours. It then tested at the very low end of thee good emissions band and the cutoff only worked with the next higher bias voltage than specd. Two of the electrolytics were leaking, one badly. I restuffed the electrolytic cans and most voltages were close, but the HV was 6KV instead of the specd 8.5KV. With only the electrolytics and 1B3, it did show a raster
. I cleaned the chassis and hooked a DVD player RF signal on channel 3 and got the first image. Lots of problems that I hoped recapping and out-of-spec resistors would fix. But, all the sections of the set worked and even got vertical and horizontal sync!
