Hallicrafters Model 820
This is the one I scored in Powell, OH this past December. The seller did the evil rotten "plug it in and try it." He reported a loud hum at all volume levels. I did a proper soft start and confirmed the filters were all bad.
Forward to now. I did a full recap. The tube lit up nicely and the horizontal was slightly off (adjusting the coil did it). I do have severe vertical foldover, so I'm not ruling out the possibility of bad resistors or putting in a wrong value cap. There are the before pics posted to my site. I had to eliminate one of the filter cans completely since the replacements would not fit, plus, if I added a terminal strip, I could eliminate some of the clutter underneath. I chose the easy way. The other cap was restuffed with two of the three values. I'll keep you posted here and on my website.
Here is a crappy vidcap of the set when I got it.
