US Navy signal generator

[Moses]

I was wondering if there were precious metals in this machine.Its made by The Davon company. thanks Gypsy scrapper

Wow! Machines with real crystal oscillators. That takes me back.

Haven’t opened one since maybe 1983. If I remember correctly, and sometimes I do not, many of the solder pads, on both the boards and switches, should be silver plated.

Some of the capacitors may have silver foils. Most, however, will be aluminum foil.

This signal generator was definitely not the best the military had to offer. It was, however, very durable. It was found in electronic repair shops in the Army, Navy, and Marines, to include Reserve units.

If working, or even repairable, it could be worth a few hundred $$ to the right collector of military electronics.

Have fun.

Time for more coffee.

I have most of the parts to a US signal generator from the 40´s. Its for calibrating radar and have a 30 cm silver-plated radio signal emitting tube for generating the signal. inside its mica cap that should contain silver. In Principe its the emitter part of a radar system without antenna and its electronic. Laying in an other place together with the manual. will check up its code and name. If any is interested of this stuff contact me. Have the tubes and crystals as well. Perfect if you want to cook someone so not to play with.

Oh, the toys we played with. Got the model # and manufacturer? Might have had to repair one of those, too. Those multilayered manual switches were downright annoying.
