Warning: Zapping can do serious and permanent damage to your organ! If you are considering this procedure, please, please understand exactly what your are doing. I, personally, try to avoid zapping if at all possible. Zapping scares me, and I've also found that it tends to be a temporary cure (particularly if you move your organ very much.) IMHO, if you've got MetallicFuzz in your organ, the proper solution is to open things up and clean it out. (See, for example, HowToRebuildTheVibratoScanner, and the section How to Clean the Percussion Switch Assembly in PercussionTroubleshooting.)

Putting large amounts of current through things like the ToneGenerator pickup coils is almost guaranteed to make them unhappy. Arcing in the key-contacts of your manual is also a bad thing, for obvious reasons.

Power Sources for Zapping

Probably the safest of juice for zapping is a regular "transistor" nine volt battery. Connect it up so that it drives current through the short you'd like to get rid of, and leave it hooked up for a few seconds. Repeat if neccessary.

Sometimes nine volts is not enough. You can try two batteries in series for eighteen volts (or three batteries, or ...)

Some people suggest using the plate supply voltage B+ to do the zapping. I would suggest you think twice (or more) before resorting to this. If you do try it, keep in mind that HammondsCanKillYou: B+ is a lethal voltage. It is also highly suggested that you use a resistor (10 or 20 kilo-ohms) in series with the B+ to limit the maximum zap current --- this is both to protect your pre-amp's power supply and to prevent arc-welding within whatever it is you're zapping. (Never zap directly from an electrolytic capacitor.)
