Got the SF2 Cab home - starting the build...

OUCH!!
It really doesn't have anything to do with the carpet. Tubes can built up residual charges, and a single discharge just doesn't get it all the way.

At least you had one hand in a pocket when you hooked it back up. RIGHT???

I wish.

Well then count yourself lucky - very lucky. You apparently weren't touching a grounded object. Voltage passing from one hand to the other GROUNDED hand will pass over your chest, and thus, your heart. This can act like a defibrillator and stop your heart. I'll ask you another question, were you alone when this happened? I surely hope not.

When I took my circuits 2 lab in college, we were given a long lecture the first session about what to do and what not to do when working with high voltage. The single best advice I ever heard was "keep one hand in a pocket".

I was not alone. I told my wife that I was going to hook stuff up downstairs and to check on me in a bit.


I did discharge it with no watch or wedding ring, a 2 ft long flat blade screwdriver and a rubber glove on. 3 or 4 times before I pulled it apart and read to discharge it again before putting it back together.

ahofle:
Man that's amazing it could build up that much charge after being disconnected for a short period.  Since these things seemingly build up huge charges on their own, why doesn't someone recycle all these old monitors to build a free energy machine or a self recharging battery or something?   :P
