Advice about a Starblitz 3602DTZ flash unit

I have acquired a Starblitz 3602DTZ which appears to be quite an all-singing/ dancing item with twin flashes (direct and bounce) and selectable dedication for a variety of cameras - incl. Pentax. It was originally used on an A3 electronic film camera.

The literature warns about trigger voltages for film era flashes being very high and therefore dangerous to use on modern DSLRs but the various tables give wildly differing data for different Starblitz units:
e.g. the 3600DS = 4-5v; 3600BTV Twin = 170v and 3200BT Twin =64v. The 'twins' look very much like being No No's. These tables don't contain the 3602DTZ Twin, which seems to be a later model and I have only found one reference to its trigger voltage being 10.6v.

Has anyone experience with it or advice about using it on a K5 or similar?

Struggling to remember the name, but there's a little device - Weiz cell? - that sits between the flash and the hot shoe and effectively reduces the trigger voltage reaching the camera whilst allowing the flash to operate in manual mode. Unfortunately this partially defeats the functionality of the flash, but I suspect a film era flash would only perform in TTL mode on a DSLR anyway.
