I discovered a loose wire in the B+ Boost circuit. Fixing that resulted in a raster


I rigged up a crude antenna and picked up this LPTV broadcast. The focus is terrible because the focus coil messes up the self focusing 8XP4 test CRT.


Hooked up to an ATSC receiver / converted box. Zero audio. However, the FM radio reception is pretty good. It wouldn't be the first time a vintage TV didn't like my converter box.


I dug out an unmarked, rebuilt 17" CRT and hooked it up.


This is the best focus I could manage. Could be this CRT isn't compatible with this set or maybe the focus circuit needs some work.
