Also, for the transistors... well. first of all. Don't use transistors, use MOSFETS. They don't need significant current to switch on (in the nanoamps). and as for the type you need. You want a MOSFET with the lowest gate capacitance. What this means is that the MOSFET will switch on faster when the required voltage is applied to it. The gate is essentially a capacitor, and we know that small caps charge up faster than large ones. This is the only factor that will determine how fast the MOSFET can switch on and off. Theoretically, a MOSFET has infinite rise time if you could charge it up with an infinite voltage spike. So the MOSFETs are as close to a switch as we will get as far as I understand. Also, get something that can handle at least 100V at 1A. They are cheap and readily available at RadioShack for about $2.00 each.

the pics of the test i did last night as i said i would post

is

how are you hooking those wires up exactly?

i hooked up the wires like this

the steel welding wire to the volt meter  only 1 end the other end i touched

the speeker wire was wound bifolar and connected togather at 1 end and i touched the other i touched with my finger  and the last wire was to the volt meter so there was no connection between the steel wire and the speeker wire some how the small voltage from me went from steel to copper without any connection between

strange but it worked as you can see in the pic

is

Nice proof. And you were going to leave? I think not after this. You are now a permanent resident.
Welcome to the fray.
