Hmm ok, I'm looking at http://www.nteinc.com/Web_pgs/hvr.html and it looks
like NTE513 will do, but could you confirm ?
Prv is 45kv -- nor prob. If is 5mA, and Vf is 75V@50mA

I was worried at first that Vf was too small -- but if that's voltage DROP
across the diode, than smaller is better, right ?

BUT -- checking Mouser, they want $33.04 for it. Yikes. I've got 2 SK7333's
on order. THey are backordered 3 weeks -- but I'll wait for that price
difference.

Wow -- looks like Thompson Consumer doesn't have any sort of web site. I see
a more easily available sk7330, but no specs on it. Damn.
