Another question . . . based on the original one that included the 
OM-2[S,sp] in the list of bodies . . .

What is the trigger voltage of the Quick-Auto 300/310?

Reason for question:
High trigger voltages fry bodies newer than the OM-1n/2n.

To amplify on the remarks about NOT using NiCd cells in the QA-300/310, 
this extends to NiMH cells also; they CANNOT be used in them either.  Same 
applies to the original Bounce Grip (made for the QA, not the T's).  NiCd 
and NiMH cells will burn up their electronics.  The problem with all of 
these is the low internal resistance of NiCd and NiMH cells . . . which is 
what allows them to deliver very high current on demand . . . the BG[1] and 
QA-300/310 rely on the higher internal resistance of cells such as 
alkalines (as compared to NiCad or NiMH) to limit that current.
