vector monitor drive board wanted- P327 WG preferably....

I need a P327 transistor driver board for a test I'd like to try-using
2 boards together in a push-pull configuration.

Possible advantages are:
max voltage across yoke2X; doubles "kick" to yoke-2X beam max speed
current always draws evenly from both supplies
power dissapation per transistor is halved(each output at 1/2 voltage)
should be able to double power supply votage-for a total 4X more kick on yoke
one board just used as a "slave" to first

Disadvantages:
EIGHT output transistors needed!
boards need to be modded-the current sense circuit needs to be changed
???others???

Anyway, if anyone has a spare P327 or 324?? laying around, let me know...
