Odd/collectible tubes for trade.

Offering a bunch of duplicates from my tube collection. Primarily looking to
swap for collectible tubes from other folk's excess stock, but will consider
reasonable cash offers. If interested, PM me..

RCA 8844. 1/2" vidicon used in later model CCTV applications. NOS. 6
available.

C1K thyratrons. Electrons, Inc. NOS in battered boxes. 4 available.


NL-7703 Ignitron National Electronics Capacitor discharge/crowbar
switch. Just the thing for building a
quartershrinker/cancrusher/railgun. Switches up to 20 kV, 35 kA. Locals
(NJ) only, unless you have a legal way to ship them. Lots of liquid
mercury in these guys.

WL-579B Westinghouse HV vacuum rectifier. Pure tungsten filament, might
make a nice night light. Used, FOK. 4 available.

5820 Image Orthicon. RCA. Nice clean example, with the celluloid packing
tube.

CV100 British "trigatron" spark gap radar pulser. NOS military boxes. 2
available

CX1622 EEV. modern (still in production) large glass deuterium thyratron
used in lasers and medical gear. NOS.

RCA 5890 A low-runner oddball. A "beam pentode" shunt regulator used
(exclusively?) in early RCA theater projection TV gear. Looks like
exactly what it is, a CRT (5TP-) electron gun, firing into an anode
assembly from a 2X2A. Used, FOK. Tests OK as a 5TP4 on a CRT tester, for
whatever that's worth.

Burroughs B5991/8422 nixie tubes. Pulls from HP test gear (counters and
IDVMs) LOTS available.

73,
