Quoted from Kramertheman:On another note, Would a 22 microfarad capacitor work in the backbox to replace the 25 microfarad capactor that is called for? I cant see any ill effects but I would assume the original cap is bad and I can't find a 25 microfarad exact replacement.
Kramertheman
Normal replacement procedures as relating to electrolytic capacitors is to step up to the next highest standard value if you can't find the original value.
Since the original is 25 uf, the next step up logically is 33 uf. However, an EM pinball is not rocket science and tolerances on components can vary. You should still be ok using a 22 uf one.
