Thanks, Chuck. You are correct about the source of the 6V info. I vaguely
recall that I tried the Braun in the hot shoe when I first got the E-510,
and it worked. I then got worried and decided not to do it any more. So
far as I can tell, no harm done. I will look into the Wein Safe-Sync. I
had rather not create a problem. But, a modern flash unit would probably be
a better investment.
