5 Germanium PNP transistor for CDV 700 Victoreen and Lionel Geiger counter

Up for sale this week I have 5 Transistors that will fixyour CDV 700 Victoreen, Electro Neutronics 6b or Lionel model 6 Geiger counter if they are bad,they take 2 or 3 so you get a couple extras. The original transistors develop and grow whiskers inside and stop working over timethis may be why your Geiger counter does not work.(see pics). I know they work in the Victoreen Electro Neutronics and Lionel model 6 counters. I have repaired a bunch with these with these transistors and they work perfect. They may work in the other 700 models. I can't guarantee these will fix yours, you may have other problemsbut they fixed several of mine. You have to make sure the wire that is attached ( the middle wire) to the case of the transistor goes in B marked on thecircuitboard of some models.If you can solder they are not that hard to change, just make sure you mark where the wires go back and take pictures. Thanks for looking and keep some spares!!!

Unfortunately, the tin plating that is applied to the base metal of the encapsulation exhibits the rather surprising phenomenon of growing whiskers that ultimately make contact with electrodes inside the can. These whiskers are many times thinner than a human hair, but they are able to pass a current that will interfere with the operation of the transistor.
