I haven't had a chance to pull out the board from Future Spa to take a pic of it, but I will get around to it and send you a link!
I am not looking for pictures of a particular board. I'm looking for a picture of the back side of the hinged wood panel that holds all of the backbox lighting. I'm trying to determine where the little 2"x2" AUX DRIVERS (not Aux Lamp Drivers--a different thing) are located on various ones. Attached is a sample of the type of picture I'm looking for.
I have 7 Bally machines of this era, from Strikes and Spares through Centaur. Do all of them have this issue and will this board set address the issue in all of them? I was hoping to convert them all eventually to LEDs.
As long as they are late 70's / early 80's Bally (or Stern) Solid State systems using the AS-2518-23 / AS-2518-14 or STERN LDA-100 lamp driver boards utilizing SCR's of type MCR-106 and 2N5060 / 2N5064, then they will exhibit this problem.
Ultimately, I would take one of these for each applicable machine (up to 10).
Awesome! Looks like I have enough requests, even if only 50% follow through, to make this a go. Finalizing layout, and then need to pick the right fab and get some of the adaptor boards produced. Thanks for everyone's interest!
