MC14514BCP replaces the old MC14514 IC's on the bally lamp driver board (and other pinball boards).
if your bally or stern lamp driver board is not working, and you have replaced faulty SCR's, etc. and the board still doesn't work, then the likely issue is with one or more of the 4 Multiplexor ICs on the board. This is a replacement IC and works perfectly. I have successfully repaired many lamp driver boards with these.
These are difficult to find, but I managed to find a new stock of them.
FREE POSTAGE
About me: I am a pinball fanatic and I do a lot of repair and maintenance work on pinball machines. I buy parts in bulk and offer surplus stock for sale on ebay to other pinball owners. I do it more as a service, rather than to make money, I aim to keep prices as low as possible. Ebay and paypal fees and postage costs are the bulk of the cost for many of my cheaper items.
I also make various pinball electronic kits. Currently available: Bally SS LED Anti Flicker kits. Coming Soon: LED Bally Score Displays.
