B> HeNe PSUs

So I am in the market for some cheap PSUs. I'd prefer 110V mains, but I am willing to negotiate.

I need:

6.5mA PSU in the 2.45-2.85KVDC range (anywhere in there)
5mA around 1.3-1.9KVDC
5.25mA 1800VDC
Adjustable around 4.5-6. I need one that I can pot adjust with my REO to find a perfect "sweet-spot"

Ebay is probably going to be your best bet. I've seen PSs with HeNes for 30-40 if you watch for them.

I've got like a dozen but they are all for tubes and finding extras is difficult.

Sam has them but his are about $40-50 each and up.

Are you looking for Lab or brick?

I'll keep my eyes open for you.
