Ooh, PSU looks ideal for a photomultiplier tube - been wondering about
how to power the one I've got. (Will need multiplier - tube runs at 2.4kV.)

Two tubes in the project, but both vacuum ;-) [Experiment to see if
low-energy x-rays (10-25kV) or gamma rays (0.5 uCi Co60 sealed source)
can cause scintillation in a chunk of native scheelite. If nothing
visible, will use PMT as detector.]

The boards come in multiples of 3 - I'd like to order one of each of the three boards (I'm in the UK), not 3 of each (i.e. 9 total) as its quite expensive to order otherwise,

Are there two other UK/Europe types who would share costs with me - I've done some larger group buys before (e.g. Pete Hand's excellent clocks).

Cheers

Anyone interested on a similar group buy in the US? I would need only one of each board. And I live in NJ.
