Quoted from vid1900:Most of it applies.
I see you got rid of the 2 varos and replaced them with a single bridge rectifier, that's a good replacement tip.

So, since I seem to be allergic to buying new crap I always buy low priced used crap! At TPF last month I got this gem of a Stern 100 board that I have never dealt with before. I'm in the process of rebuilding it and need to know where the fuse should go. It doesn't look like any other one I have seen pics of. A link to a schematic would be really helpful...

IMG_3756.JPGYup. To all that. After I finish pulling components and pins it gets a thorough scrub down and inspection of all traces. Can't wait to figure out what all the extra wires are soldered on the bottom.
Quoted from viperrwk:+1 to these. By the time you're done you'll have a nice clean new-like board.
And since you pulled it off, replace the LM323 with one of these:

Already got GPE's version, but thanks for the heads up.

Working on my 6th S/S and have yet to buy a new board. I've bought a couple of CPUs and score displays off e-pay and most everything else either came with the machine or I picked up at the TPF swap meets. I love used.

Did that. I have come across several different solenoid schematics that way and none of them sport a revision letter. They are odd diagrams, broken into sections by voltage. Makes sense, I guess. Just not used to looking at them that way. Time will tell if it is helpful or not.

Quoted from indypinhead:When replacing the 330ohm and 120ohm restistors on the Bally AS-2518-22 driver board, what wattages should be used?
R-35 is 1 watt, R-51 and 56 should be 1/2 watt and all others are 1/4 watt.
