I have a Sunpak Auto322 flash from my film days on my Pentax MX, that I have used a few times on my recently bought K20D. Now after some research I learn that my trusty 322 could fry the K20D through the hotshoe. So if I use a flash bracket and the cable from 322 into the PC port on the K20D am I also endangering the K20D?
That or I get voltage protector for the flash so it can't backfeed high voltage into the hotshoe.

I just checked the voltage output at the hotshoe mount on my Sunpak Auto322, and I get 175v to 179v. At first I thought that would be only when the flash fires, but that value is present whenever the flash is on. So,...no more 322 on my K20D.
