Sylvania 1N358 Coaxial Cartridge Diode

Hard to find Sylvania 1N358 cartridge diode, used condition. The 1N358 is an obscure tripolar RF frequency diode in a coaxial package. This coaxial package was designed to be inserted into a complex socket which would leave the business end of the diode poking into a hollow waveguide. This is a fairly early semiconductor part, and was first released in 1955.

Burroughs BX-1000 Decade Counter Tube

BX-1000 Beam-X Switch beam switching tube, new condition in white carton. The BX-1000 is a complicated 10 stage decade counter tube that can be coupled directly to a Nixie tube display to create a transistor free counting and display system. Each tube contains 10 cylindrical magnets that direct the flow of electrons within the device, a switching grid 'bumps' an electron beam from magnet to magnet in a circular fashion inside the envelope. Though these were actually manufactured by Burroughs, the example for sale here has been crudely re-printed with the brand name "Electronic Enterprises".
