Talk:Bally/Stern

feel that the actual dimensions listed in this section are misleading and are not correct in that it's more important to get the gap correct by feel than by saying "I adjusted this switch to 1/64" (which is too close for any switch IMO) - Scochar

I agree about the "feel", but what actual dimension should be given to someone who can't get the feel correct? -jpal

Well, the bally manuals recommend 1/16".

So change it. :)

"the One" also recommends 1/16". Hibs

re: Diodes on bally stern - I think you should revert it back, there's no more investigation needed. Bally used it from the factory. Stern used it interchangeably. While I usually put 1n4004's back on because I have a ton of them due to their universal use in wpc etc. and on coils, the issue raised by the RGP discussion of this is completely wrong..... you're not pumping more than 5 volts through it (the PIA is driving it) and you're not putting more than 0.2 amps through it, either. I forget the spec offhand for the PIA's max current output capability, but I doubt it's getting anywhere near 0.2 amp, and there's current limiting resistors on the mpu board anyway on the strobes and returns.
