GE 800D restoration

[bandersen]

I finally got back to this set over the last week. I ended up pulling the picture tube so I could get at the last few caps. Still tricky but I managed.





I popped in a 5AXP4 test CRT, crossed my fingers and powered it up. Crackle from the speaker, high pitched whine and a faint raster.



B+ was a bit low using a 40 ohm resistor and I was getting quite hot. Dropping it down to 8 ohms got B+ close and the image and sound improved.

Popped in a set of good tubes and the image improved more, but sync is non-existant. Also have the contrast all the way up to get an image and weak sound. Signal at the sync clipper is about 80% low so I'm thinking RF or IF gain is off. Will check resistors next.
