Geiger Müller Tube

(TUR) CK1026
Here is your chance to obtain the basic building block for a Beta particle and gamma ray detector. These halogen -quenched thin wall Geiger tubes, made by Raytheon, are left overs from production in the 60's but have virtually unlimited life. Brand new, never used.

We found loads of info on the internet concerning thesetubes and have included some basics with your purchase to help youget a start. We found the CK1026 sold for about $25 on other sites.

This tube is for Gamma radiation only, with a 760 volt Geiger threshold and a 900 volt operating voltage. Typical background=60 counts per minute.

Please see the following link for more info.
*** SOLD OUT ***
Our Geiger tubes were produced in the 1950s we believe and are very delicate. The glass is inheriently thin creating a situation for damage to occur unless the most extreme measures are taken in handling and installation. Because we have no control over how you the experimenter will handle this product, no guarantee what-so-ever is implied or expressed as to the durability, function or use of this tube. You can be assured they are new and never used when shipped and since Halogen quenched tubes have a virtually unlimited life, if care is taken, you should have no problem constructing your own geiger counter.
WWII Jammer Transceiver / Receiver from 1944!
Rare, WWII jammer transceiver / receiver from 1944. New in the original box!! Apparently, one of the first iterations of a number of jammer projects initiated during the war. Covers 14 to 50 MHz. Designed to allow listening to locate German ground transmissions and then transmit to jam them.

Appears to be a TRF receiver. Transmitter appears to be a 6J5 oscillator, 6AG7 driver and an 807 final. Should be good for a very conservative 20 watts output. Uses a combination of a 2X2 and a 931A photomultiplier tube as a noise generator producing about a 40 - 150 KHz wide signal. Also has a 5Y3 and 5R4 rectifier. 11 tubes total.

Operates on 80 or 115v AC, 400 to 2600 Hz. Includes spare fuses, pilot lights, tuning indicator lamp and a brief operating manual. No technical manual available.

Measures 10-1/4"W x 7-7/8"H x 21-3/4"L.

Federal Telegraph
Automatic Bearing Indicator
(EQP) CFT55084
Perhaps the only Automatic Bearing Indicators in existence today and new in the crates to boot. Made by Federal Telegraph for WWII and delivered March 31, 1942, right in the thick of it. New technology was being pushed to the edge of the envelope. I suspect they never were adopted as standard equipment. Includes prototype style handmade manual (original and marked restricted of course) with each scope.

Basic theory of operation is a small 1/8 HP 1140 rpm motor drives a goniometer directly and a set of magnetic deflection coils. A 5BP1 CRT is positioned inside the rotating deflection coils and thereby deflected. An optical system consists of an illuminated scale and a mirror so positioned that the reflection of the scale appears to coincide with the pattern obtained on the screen of the CRT.

The manual indicates the following voltages are required:  -800v DC, -650v DC, -160v DC, -135v DC, 6.3v AC and 11 5vac 60 Hz. Only four available. 120 pounds gross weight. 46" long.

Crated weight 1,460 pounds. APS-20 radar systems were the heart of WWII surveillance, used in the Boeing B-17 Flying Fortress and P2V-2S Neptune.

This new and complete unit contains all of the items featured on this page plus many more! In today’s dollars the CG-35 sold for $250,000 about 60 years ago. We have no nomenclature on this unit and can supply no operational instruction or advice. Surplus Sales is not responsible for the use or misuse of this apparatus. Only qualified personnel should attempt any experimentation involving the CG-35. May contain products considered hazardous to today’s standards.

We are thinning the herd. I have 50 units in stock and will conduct a sale until 25 have been sold. This is a once in a lifetime chance to own both a piece of history and an excellent building block to many different energy related projects.

Norden Bombsight
CP17 / APA-46
(EQP) CP17/APA-46
Rate end computer made by Burroughs Adding Machine Company. Weapons systems technology of 1948 made for US Army Air Force. This is the gyro end of the bombsight. We are not implying this is a complete system. New in the crate.

Several years back the Smithsonian Museum acquired one of our Norden Bomb Sight gyros to restore the Enola Gay to its original condition. During restoration, a technician noticed the gyro installed in the aircraft was dated in the 1950's and could not have been the model in the original installation. Since our gyros are the correct model and date, the switch was made.
