Picked up Ms. Pac-Man (cabaret) from Craigs List ad on 12/9/09:
This is what the 13" G07-FBO monitor looked like when I bought it. Notice the curl on the right side of the screen and the split sprites. Ordered full deluxe cap kit with extras from Bob Roberts on 12/11/09:
Notice the curl still present in the lower left side of screen after horiz. freq adjustment and replacement of 1F chip on PCB to clear up sprite issue:
Picture after monitor rebuild: Picture is sharper, better colors & even though it looks a little distorted in the pic, the lines are perfectly straight now with no curl anywhere.
PCB with 1F chip circled. Brought board to Dick Millikan on 12/11/09 and he socketed & replaced chip which cleared up the split sprite issue:
Here's the coin counter 72,008:
Here's the broken switch on the joystick which I replaced with a new one from Bob Roberts:

Here's what it looks like in the office arcade now:
Full cap kit w/new filter cap, flyback, HOT & regulator transistor installed on Ms Pac-Man Electrohome G-07 FBO 12/15/09-12/16/09. Found a bad solder joint on C412 and C517 & C518 were flip flopped in the wrong positions. Reflowed solder on all connector pins (pulled old solder out & replaced with new). Didn't come with keys so I drilled the locks and replaced with new ones from BR along with a new replacement power cord also from BR. I also added swivel locking wheels in the front & stationary wheels in the back so I can move it around easier when I need to.
1/31/10...Ms. Pac-Man died: It started with a popping sound from the speaker when I powered it up and a broad vertical line of distortion that swept from right to left slowly with a crackle in the speaker when I played it. I pulled the fuses, cleaned & replaced them. No picture on screen after that.
2/1/10 replaced 4-fuse holder with a brand new one and it works perfect now!
Old dirty fuse holder:
Shiny new fuse holder from Bob Roberts:
4/15/10 Ms Pac has been making a loud buzzing sound every once in a while. When I moved the edge connector slightly it would go away. Finally had enough and replaced the original connector with Molex from BR (also finally cleaned inside of cab). No more buzzing!
Here's the new edge connector half way done:
Here it is completed and back on the PCB:
