HGM 5
Ok ive got a HGM 5 and a HGM with a 903 tube( I think thats right).
Ive got 3 PSUs all of them are messed up or burned up...
So the ? is what else is out there that can run these tubes? Like a lexel psu or somthing like that? Or do I just need to sell the tubes?
Thanks!

You blew up ALL THREE power supplies? Dude... You're starting to scare me!
But seriously - those PSU's are robust. The passbank is easy to repair, and even the current transformer should be an off-the-shelf item. Same thing with the output caps. Get in touch with Bruce Rodgers; I'm sure he can steer you to the right components.
In principle I think you could run an HGM 5 head off a Lexel 85 power supply, as the tubes are roughly the same size. Then too, a Coherent I-70 PSU would probably work as well, and I know you've got one of those sitting on the shelf. (So do I, in fact...) But you'd be better off repairing one (or more) of the original power supplies.

Something is horribly wrong if you popped 3 HGM PSUS. Get in touch with BR and see what is wrong.

Well I should have gave more detail..
The first one was working fine, when the card fell in to the HV and thats how that one died..
2nd one I hooked everything up had it running, and just when I thought, alright it works..one for the trans. welded its self to the frame..
3rd.. is still unknown...might be a bad passbank..
I really need a layout of how the PSU is wired.
