And whether it's the power supply or the CRT or the door hinges, it will be a whole lot easier to help if

with their own "guts," to various levels. Therefore, what you have may actually be something like a Bally, original or modified by ACE.
Please, please post photos, inside and out, in as much detail as you can.
It will not only help us to help you, but it will add to our own knowledge and the archives of this site.
