Re: [TCML] Old HV diode H-386 by Varo



Thanks much, DC. I really appreciate you taking the time to help out. I will be writing soon about your reactor cores.

These were rated around 20 kV at 50 mA. I used these in a string to charge
Van de Graaff belts.  Presently we have upgraded to a more modern version.
They were very reliable in operation.  Varo also made some rated for 60 kV
which they used in X-ray multipliers.

Does anyone have any information about another diode I have? It is 3.25"
long and .25" in diameter and is a VARO H-386. Varo was sold a very long
time ago and the new version of the company no longer manufactures them and has no data on their web site. I have searched everything I can on the web
with no luck. I even wrote to VARO and asked if they can provide any
information. I did locate one tiny tidbit that says these are supposed to be
high voltage, which most certainly fits the long length. Thanks for any
assistance.
