Can I zap myself biasing my tube amp??

Mark,

Biasing is done with the power on and the tubes warmed up. Make sure your meter is a good one and that the decimal point is in the right place for DC mili-volts. If you use a metal screwdriver (Not recommended for beginners) make sure it's tapped up pretty good (scotch 33 electricians tape). The potential inside an amplifier is well over 300volts and yes you can light up your world if your not careful.

If you feel at all nervous or uncomfortable take it to a hi-fi or electronic store. Usually a decent Electrician would be able to perform this task in a pinch. (Audiophile electrician preferably) good luck!

If you are worried about those close encounters of the electical kind, then truck on down to your electronics store and get a CG tuning stick. They are red plastic and if you touch it to high voltage you will not get shocked. They are used for tuning transmitter plate voltages. They're about $2.00.
But since most amps are designed so that you can bias them without any danger of getting shocked you really don't need one.
I use mine to pry open remote controls for cleaning. They don't leave marks on the plastic like screwdrivers will.

Get some help. If you have never done this before, it can be very dangerous. Just the fact that you are considering rubber boots tells me that you may be unaware of the precautions needed. The place you want the insulation is on your hands. You may not get a second chance if you make a mistake. A tenth of an amp is all the current needed to be fatal.

All the way to a wooden Box.

mythtrip... i just got the VTL IT 85, and wasn't sure about biasing either. it wasn't a big deal! i just read the directions a couple of times, and went to radio shack with the catalog numbers they referenced in the manual. i got a little plastic screwdriver at radio shack too. total cost was about $35. got home, easily took off the cage, and everything was clearly labeled on that map of the inside of the amp.... it was really easier than i thought.

good luck..
