About 6.5" long and 2.5 wide at its widest...... shaped like a WWII German hand grenade....4 pins.....not glass, all plastic (composite) Thanks Mike Hi Mike, Well, it would be a good idea to find out the exact specs of your Thyratron (I bet a lot of people don't know what the heck one of these things are!!). You can try www.russiantubes.com except these are Russian made (some still made during the Soviet era), and compare average values of these Thyratrons. However, I've never seen a plastic one (it probably isn't high voltage), most of the ones I've seen are made from ceramic, but this one could be different. I typically pay $300 USD for a specific Thyratron that is used in Copper Bromide Vapour Pulsed Wave Lasers that I work with, but a NOS one in untested condition?!?!? Does the application still exist? oh, and not ever having seen a WW2 German grenade, I'm guessing it is a cylinder of some sort with the pins probably on one end. Is there a metal ring somewhere down the center of the unit? Hope that sorta helps you out. -- Myron Samila Toronto, ON Canada Samila Racing http://204.101.251.229/myronx19 |

Just keep in mind, once the last pin is pulled. Mr. Hand Grenade is no longer your friend. Gunner KS19699-L4 SOLID STATE THYRATRON 2/68 MFD BY MOTOROLA FOR WESTERN ELECTRIC Still in original box !!

--- on the heady topic of "Thyratron" Interesting from an historical viewpoint but made obsolete by the advent of the solid-state Silicon Controlled Rectifier (SCR). I'd mount it on a marble plaque with a ceramic socket and enjoy it as a fancy curio. I did this with a 50 amp mercury vapour rectifier, besides it was simply too toxic to trash it.

Probably intended as a replacement for the mercury-vapor thyratrons WeCo used in their PBX battery chargers. Isaac |

RW Bob AZ Industrial numbers were into thousands range. Many tube types are still being mfg'd overseas, China, Russia, etc and apparently there is substantial NOS of some types around. Guitar amplifiers are a constant market since dsp technology failed to replace their sound. .... Back when I was a boy, we sucked the air out of our own vacuum tubes! |
