This thing has pretty well killed my resolve to work on televisions. I have never done so much work to get so little done on a television. Where I stand with this thing now is that the am radio only works, and I get only a very silent white noise sound for audio on FM and television. I get a raster, but no image on the screen. I've tested all of the components I can get to, and I have replaced all of the questionable parts, and put in a new lineup of tubes in the receiving/IF sections with no changes.

Trying to inject signals into the set, but my B&K analyst is just too iffy to get any results. I've been scouring ebay for a sweep generator and marker generator, but I've been outbid on all of this gear for the last month.

I'm pretty sure this set is out of alignment, as many of the circuit adjustment screws that were sealed in blue locktite have clearly been fooled with. If anyone in southeast PA has the appropriate alignment equipment that could be used to analyze this set, I'd love to see what it's issues are.

Failing that, is it possible to simply put a/v jacks into this? Here is a schematic for the 801, which has nearly identical audio/video output sections. If someone is aware of how to properly do this, I would like to know how.

All that aside, here is some of what I did do:

Here it is, the power supply for this set. Using a transformer for an RCA 12" set, a Crest power transformer, and some surplus transformer, I had enough to power the tv. It is mounted to a cake pan, and all routed out to a European-style terminal strip. You can also note the two Dale-type power resistors mounted to the angular heat sink on the top of the power supply. The whole thing weighs 35 pounds. I am still very happy that I was able to create something like this, but I need some way to continue to move forward with this set.
