Maxxum 2800 AF on or off K10D... will it kill it?

Just bought an older Maxxum 2800 AF flash off eBay and was *NOT* actually intending to ever use it on my K10D... what I wanted it for was selective lighting by hand during long nighttime exposures (so just planning on opening the shutter and then wandering around flashing various items to - hopefully subtly - light them).

Anyway, since I now have it and am invested to the epic amount of $20, I was curious if anyone knows if I can use this on the hotshoe of a K10D.

Not a big deal if I can't, just curious.

Also curious if using an extension cable like this one on eBay:
https://cgi.ebay.com/Flash-TTL-5m-Extension-Cord-Pentax-AF-540-360-FGZ-/3902...item5adb814a56
... would protect my camera from high voltage situation. I don't really know how the cables work, is it the same voltage risk to my camera as if I had it mounted directly in the hot shoe, or would I be able to get away with it.

Again, only $20 into the flash, lots more into the body so don't want to fry anything, but any experience with either this specific flash on the hotshoe or any older flash connected by an extension cord would be much appreciated.

Thanks in advance.

An Ext. cord is just that. It will carry the voltage of the flash to the camera and back and would be the same as mounting it on the camera.

This flash is not that old as it was made for the 7000 camera. Wait and see if someone who owns one replies as to the safety of mounting it. You could use a wired or wireless trigger specifically made to reduce the voltage if necessary.

The Maxxum 2800F is fine to mount on a Pentax DSLR. The max trigger voltage is 1.74V. Pentax DSLRs are rated up to 20V.
