G07 -- any point to trying to adjust out curl w/no game board attached?
I just did a cap kit, HOT and flyback on a G07 I had that was displaying some pretty serious foldover/curl. I also replaced the pots. There were some hacks done to this board on the solder side, 3 diodes and a cap were bridging some of the traces. I undid all of these hacks as part of the cap kit. I also did the C303/C501 mod as recommended by Bob Roberts.
Hooked the monitor up to my ISO (which is on a test bench but has no harness hooked up to it yet -- it's just 120vac -> ISO -> monitor) and turned up the screen control until I could see white raster -- success! However, there's still a bit of curl. I checked the B+ and it's at like 119.8 -- close enough for jazz. I tweaked the other pots but couldn't get rid of the tiny bit of curl at the top.
A: Is there any point in me trying to adjust out the curl w/o any board attached? Is the white box/raster enough?
B: Bob's notes say to adjust B+ until there's no curl. Does this mean to forget trying to get it as close to 120vdc as possible and just look at the curl, tweaking it until the curl is gone?
