It sounds like one or more loose electrical connections somewhere. Did you try cleaning the contacts in the hot shoe and on the flash? If not, do so. If so, I guess it depends on how adventurous you are and how easy the flash is to get open.
For the dim pre-flash, I can see "maybe" that this would be involved... but the zoom problem occurs (occurred) whether or not the flash was attached to a camera.
If it's not the shoe contacts, my first suspect would be the wires/ connections that lead from the contacts in the foot up to the circuit board. Those should be easy to fix on the foot end, but likely not on the circuit board end (likely to be a flexible circuit board that would probably be damaged by normal soldering with a typical iron).
I guess I just need to write up a good letter, cross my fingers, and send it in. (sigh). Good thing I have a few spares laying around.
It doesn't sound like the wiring from the circuit board to the non- camera components, like the tube.
Yup, I agree - seems more like a logic problem (the tube not being told the right thing to do) rather than a tube issue (tube UNABLE to do what it is told).
