No worries mate!

Glad you got that thing "up" (pun intended :P ) and running!

Yeah the driver packs are a thing keithy. I am still planning on either building my own valveblock out of COTS parts and/or the drive pack from COTS. It should not be hard at all since all it seems to do is be an amplifier to the original signals from the EAS computer. A handfull of transistors of maybe fet's should to the trick. Plonk them on a whopping big heat shield in an air tight box and bob's your uncle.
