I have also been trying to get information about safe flash voltages, I sent an email to Sunpak concerning my old flash unit, here is the email I sent and the reply I received back...
I measured the voltage at the pin on this flash and found it to be 42 volts...
I have been using the flash with no problems showing..
The 3600 is virtually the same as Sunpak 522, though I have heard reports of much higher voltages on the pin of the 522...

Dear Sir,
I have the Sunpak Auto Zoom 3600 Thyristor Flash unit and want to use it with my New Pentax K20d DSLR camera.
The Pentax has a "X-Sync" socket that the flash sync cord will fit into, but I have been warned the the power level at the flash sync cord is too high and will destroy my camera.
I would like to know if this flash would be safe to use with this camera or not, and if possible to find out, just what is the level of voltage present at the sync cord of the 3600 flash unit?
I bought this wonderful flash new many years ago and I have used it for many years on my Pentax Film camera, I really would like to be able to continue using the flash with the new Pentax DSLR if it is safe to do so without damaging the Pentax K20d.
Thanks for any help that you can forward to me.
Answer back...
