I pulled out the G07 in my Centipede Cabaret and did a complete cap kit that I ordered from Bob Roberts. I also replaced the flyback and did his "curl mod." After I threw it back together everything worked and looked fine except for a couple things.

1) I can't expand the horizontal width to fill the screen. The coil looks fine and I was able to get a LITTLE bit out of it, but not enough. I've already ordered a width cap kit from Bob Roberts, hoping that'll fix it.

2) There seems to be a tiny curl in the upper left hand corner of the picture that I can't seem to get rid of. I've adjusted all of the adjustments (h. freq, positions, v. lin, etc) and it just won't go away.

3) On the left side of the picture, the picture seems to bend/bow inwards ever so slightly, but it's noticeable enough to me that it bothers me.

Aside from ordering the width cap kit, I've also ordered a new width coil and replacement caps for c301 and c520 that weren't included in the cap kit (as pointed out by Ken Layton in this thread http://forums.arcade-museum.com/showthread.php?t=58522&highlight=g07+included)

I'm hoping the combination of all of these things will fix most of my issues, but can anyone chime in and add anything else that might help and/or I could try while waiting for the parts? Oh and the B+ is right at 120v

Thanks!

-Jim

Sometimes, games just don't fill the entire screen. Moon Patrol is a good example of this. The game fits in a square shape on monitors that don't have a width pot, and the width coil is at its max. It doesn't look 'bad' but a lot of people like it to completely fill the screen.

How does it look with the blue surround on it? That should cover a bit.
 
Sorry, I didn't mean for that to come off that way. In his second sentence, he says "I also replaced the flyback and did his "curl mod." After I threw it back together everything worked and looked fine except for a couple things."

Nah, I just said "Okay" because it was faster than typing "Sorry, I'm a dumbass who skimmed through the original post and missed that part..."
 
Ran and did this during lunch and worked like a charm. Just note that C303 is a 0.1uf (labelled 104) mylar cap that needs to be placed in C501. If you see it's still curled just tweak the 'H FREQ' pot and it'll become straight as an arrow. :)
