Thanks, I'll take you up on that offer
This set has become rather frustrating. Especially since it was working fairly well on mostly original components. Now that it's been fully recapped, I still have some nagging issues remaining.

1. Excessive width. I need to reduce the width by about 30% so something has to be way off. I've replaced all the caps and checked/replaced all resistors. Also swapped the 6BG6 HOT and adjusted the drive and width controls. All that had minimal effect. Time to check the few mica caps I guess.

2. The tuner has some nasty issues. When adjusting the fine tuning the picture cuts out. I have to tweak the channel knob to get a clean picture. I have cleaned the contacts but I think it's time to pull it out for a closer inspection.

3. I don't get any picture until the brightness is about 3/4 clockwise. The CRT tests very good but the cutoff test stinks. Perhaps I need to alter the grid bias ?

4. Sound stinks. Hopefully it's just an alignment issue.

Oh well, if it was easy it wouldn't be much of a challenge now would it
