Nice to see your progress.

Could be going south, but I'd make sure all the horizontal adjustments, B+ voltages, and H output tube voltages/currents/waveforms are right first.

[Eric H]

Well if you have a replacement then swapping it in to see if that fixes it isn't all that hard, but first, have you swapped the 1B3 Rectifier yet?

[Radiotronman]

Yes, uve tried three different 1b3 tubes s and no change.

[kramden66]

Did you check or replace the doorknob cap? That can load voltage down if leaking

[Radiotronman]

I did a continuity check to see if shorted, but nothing. I don't have another to sub in to see if it's lesky. I believe it's the common 500mmf Orange cap.b I tried the set with it disconnected and no difference. Do you think that's it? Where can I find another?

[kramden66]

Not sure I had high voltage taken away from doorknobs but I think if disconnected it would work if it was shorter. Try the fly replacement

[Radiotronman]

Ok thanks. I may pull out my b-k tv analyst and give that a whirl too. I'll also try replacing the flyback!

[Radiotronman]

So I finally got around to working on the cabinet some more. I grain filled the veneer and replaced some missing trim pieces. I applied some red mahogany stain and some mohawk brown mahogany toner. I ran out of toner and would like to apply an even coat over the entire case to give it a rich look. This is it so far...

[ChrisW6ATV]

It looks good!

[Radiotronman]

Ok, so the cabinet is now finished. I'll wax it and polish it in a week or so. Now back to the chassis....

Nice job! I prefer a finish a little darker and richer over lighter.

[Radiotronman]

The originally finish was darker, just like how I did it. I try to get every set as close as I can to the original colors.
