I have two K7000 chassis. #1 has a jacked up image (http://forums.arcade-museum.com/showthread.php?t=248925), but the width is fine. I've capped it, but not replaced the fly. #2 has a great image (capped + fly), but the image is way too wide. Probably 2" off either side. Both width coils seem to work — I can see the image size change, but can't bring it in enough.
All I want is one chassis that works 100%. Seems like it's easier to fix the width on #2 than figure out what's up with #1.
Chassis #1 has a .39uf cap at C38, plus another cap soldered on the underside. Chassis #2 has a single .39uf cap at C38.
I swapped the cap on the underside of #1 to #2. No change. I swapped C38 from #1 to #2, metering them both when they were out. Both metered good, but the image is still too wide on chassis #2.
I don't have other width caps for this thing, but I'm not sure that's what is wrong. Having the same caps work on one chassis and not the other tells me that something else is wrong, but I'm not sure what. B+ measures 130v on the near (furthest away from the tube) end of R302, which looks good to me.
What else should I be looking at. HOT? Or just track down width caps and hope that brings it in enough?
