More caution may be needed than I had thought. Still I think most
of them with voltage problems are pretty old and why would one want
to hook up some old Kalimar garage sale bait to a $1000 plus camera
anyway? Here's a list of strobes that there are reports on:

I would be inclined to draw the line at about 24v.

Actually, Pentax says the camera is OK up to 600 hundred volts (seems optimistic based on the reports). There are a lot of good old Vivitar 383s out there, though, and you wouldn't want to risk with that high-voltage unit. The 285s are OK, though. Here's a comment from a Pentax user:

Ancient You say? Some current Unomat models (B20, B24) still have
170V voltage...

I think you'd have to be using some real ancient age stuff to run
into the flash trigger voltage problem. Back in the day cameras
used a physical metal contact switch inside the camera to fire the
flash. They were pretty robust, but could get burnt. A high
switching voltage flash could overcome a dirty switch for a longer
time, but then a technician would have to open up the camera and
clean or replace the contacts. Solid state switches started to
replace these 30 years ago and I doubt any high switching voltage
flashes have been produced for 25 years or more.
