Hi;
The most important item for any game is a clean source of power, this
will give the game the best chance for survival. Rebuild the
powerbrick and A/R II first and foremost.
Next is to rebuild the monitor as those electrolytic caps are almost
30 years old and most likely out of specs. While you are at it,
inspect the chassis for other components that look beat and replace
them as well.
If you don't have the necessary components, contact Bob Roberts and
purchase the kits from him, he has a very nice selection of kits, well
priced and will also include the power transistors which should be
replaced as well.
You will need a couple of items that are not included in the kit, mica
insulators, thermal compound but. He has those as well.
Once you have the P/S rebuilt, adjust the voltages (+5vdc) taking the
reading from the game PCB not the P/S outputs.
Then adjust the display according to the 6100 service manual and you
will then have one, nice game that should outlast you..... no offense
meant.
One other procedure which should be performed as well are the diode
mods that are outlined in the WG6100 FAQ's, especially when the 6100
is used in the Star Wars game, that Death Star explosion really puts a
toll on the monitor chassis!
Good luck
Jeff
