 what connectors did you use for this?  The 3-pin connector appears to have
 a standard pin pitch (about .150"), but the offset of the center one is a
 killer (about .050").

John,
 
     You could try to see if Quantum makes an adapter for their Turbo units 
for the Tseries. This only solves one half the problem!

 HV can withstand the current drawn by more than one flash unit?  Anyone
 know the answer to that one?

The limit here is probably not so much a current limit as a  heatsink limit. 
The transistors will run at high current for proportionately longer and could 
overheat especially in quick repetitive flashing. Most flashes rely on the 
fact they are only operated intermittently and so have limited heatsinking 
which can cool slowly between flashing That is one reason why Quantum 
suggests not firing your flash repetitively too often when running off their 
regular battery packs. (not turbo packs) I seem to remember the T flashes do 
have a small resistor in series with the capacitor to limit inrush current 
somewhat when running off external HV power. This limits very rapid cycling 
too!.
