TEK 519
1 GHz Bandwidth
(EQP) TEK-519
Just what you need if you work at Los Alamos and your experimenting with nuclear events..... and you need something with the speed, and so on.. oh yes, and in the 70's. No, it's not the 70's and yes this scope does have a 1 GHz bandwidth. It also has 125 ohm GR connector inputs and a tiny 2 x 6 cm screen. We suggest buying one to strip down for parts. Now your talking. Retrieve a 4CX250 and socket, blower, high and low voltage power supplies, transformers, vacuum tubes, RF connectors and more. Very well used, but a lot of life left.

5 Beam Scope
(EQP) 5BEAM
A treasure chest of goodies. Originally, a staple scope at the Los Alamos Lab, these 5 beam scopes are now out dated. Imagine that. You can fire it up for service or strip it down for parts. 5 simultaneous beams. WOW. It appears to us that +7kv and -3.5kv is all you need. The other voltages are on board. It's 19" wide x 12-1/4" high x 21" deep.

Bulky, but we can package and ship via UPS. $45 will get it almost anywhere in the lower 48. If you strip it down, here are a few of the goodies you will salvage:
  • CRT with 4-1/2" viewing area
  • Welded all aluminum flat frame chassis makes great amp or power supply cabinet. Just add sides.
  • 16 - dual A-B 1M pots with 1/4" shaft
  • 5 - single A-B pots
  • 10 - vacuum tubes
  • 2 - 6.3 vct @ 6 amp transformers
  • 5 - Glass Mike HV capacitors
  • 15 - BNC chassis jacks
