late '60s (?) Baldwin Professional

[Bogframe]

I just inherited a Baldwin Professional guitar amp. It looks/sounds good, but somewhere in this behemoth is a bad short that gave me a nasty shock when I touched the case. I'm not technician, but is there any way an ameteur can hunt down a short without burning down the house?

Look for noise suppresion capacitors on the power line input to the power transformer. Sometimes these connect to the chassis perhaps through a polarity switch and these may be shorted and causing 110 volts ac to go to the chassis.
Make sure that the amp has a grounded power cord or that the plug has not been cut off and replaced with a two-prong plug. If it only has a two wire cord, rewire it with a three wire cord, grounding the green ground wire to the chassis. I think it is especially important to have good grounding on a guitar amp so the guitar strings etc. don't go live with 110 volts ac.

If you are not much experienced in this sort of thing you may want to take it to a technician as it can be dangerous to mis-wire the power line cord or components.

Does anyone in the NYC area know where I can lug this beast to have it looked at?
