HV Component Associates offer a complete range of HV Diodes at good prices
and they will sell to individuals. For your project you could probably use
four of their 2CL2FM Silicone Diodes rated at 20kv Peak Reverse Voltage and
100ma average forware current. They are $8.00 each.

Hope this helps

About six months ago (It seems a year), I paid someone on the list for a
high-voltage rectifier circuit. They had made an MMC for me and it works
excellently, and they were talking about how I could have DC voltage and
have an assync gap and I also thought this would be great for preventing
voltage ring-up and so I took them up on the offer and to my dissapointment,
the circuit has never been forthcoming. ;-( I mentioned it three times and
I've decided to give up for two reasons ....

#1 The fellow sent me an MMC that was worth far more than I paid for it even
worth more than what I paid for the MMC after adding in what I paid for the
rectifier.

#2. The individual is just flaking out and I don't want to be a pest about
it any more. He hasn't even cashed the money order.

I guess this further makes the point that for the most part we can trust
each-other to deal honestly with each-other, *but* we are still human and
some of us tend to put things off, sometimes forever.

I hope this note to the list will motivate the person to either build the
thing or just come out and say they haven't the time to build it but I won't
be holding my breath.

This still leaves me without a rectifier and I could just guess around as to
what parts I need, or I could ask here and make sure I get tried and true
parts. (Remember the exploding MMC dabacle?)

I remember I need diodes in wheatstone config, but I think I am forgetting
something else.

The NST is a 12kv/60ma nst. Has anyone any suggestions on parts to get and
how many of these diodes to  put in series? I would guess I would want at
least 15kv of diodes to make sure I have some buffer, but I don't know about
current. Maybe I need several in parallel to distribute the current so as to
reduce over-heating. I just don't know and I don't want to guess around
because I think I would be doomed to guess poorly.

Thanks in advance.
