Mark Smith at Pentax informed me that the -DS uses a 480V, 1.2A
semiconductor device on the flash trigger. I use my Vivitar 2800
with 270V hotshoe on it without worry after I found that out.
That may be true, but if he's having a difficulty I'd use a Safe Sync
anyway. Might as well eliminate all possibilities of error.
I've heard at least 7 different values quoted supposedly from Pentax
on the DS flash trigger circuitry's voltage tolerance. I don't trust
any of them now. ;-)
