Subject: [For Sale] - Misc HV stuff for sale
Hello all!
I have a bunch of high voltage stuff for sale -
hydrogen thyratrons, vacuum pumps, books, etc...
All of this stuff is in southeast Arizona - Hereford,
AZ (zip code 85615). I welcome pickups, if anybody
lives in this area. Otherwise, I will pack it up for
you and charge you the actual shipping cost.
------------------------------------
Lot #1) Seven hydrogen thyratrons and two ceramic
sockets for them.
Six of the tubes are 4C35 hydrogen thyratrons, with
data sheets, and an example schematic that shows their
use.
These tubes are rated at 8,000 volts, 90 peak amps.
This lot also includes a JAN-8613 ceramic triode
hydrogen thyratron, which is rated at 16,000 volts,
500 peak amps, 4 peak megawatts. This is supposed to
be a more rugged replacement of the 5C22.
I did some experiments with these tubes a few years
ago, and all of them work as far as I could tell.
$60 for the set.

Lot #2) Four 5C22 hydrogen thyratrons, with data
sheets & an example schematic that shows their use.
Tubes are rated at 16,000 volts, 175 peak amps, 1.3
peak megawatts.
I believe that all of these work. I did some
experiments with them a few years ago, and they all
seemed to work.
$50 for the set.

discharge circuits up to 10,000 volts. Peak current
is 35,000 amps.
This lot includes two home-made sockets/holders for
the tubes, two 1 uF capacitors for use in trigger
circuits, and various clips and braided cables for
hooking up to the tubes.
