Austron 1250A

Austron Model 1250A New Old Stock plus out of original box, and tested. I have 1 in the original box and 2 out but tested. The original rechargable cells for battery operation have long since lost their ability to support a charge, but none have leaked. They are complete with the operations/service manual, spare parts, rear panel connector, long tool for rough frequency adjust of the crystal in the inner oven, spare fuse, and extender board for service.

They output 5 MHz, 1 MHz, and 0.1 MHz front panel BNC connector signals. There is a front panel fine frequency adjust, and they can be voltage tuned with a -5.0 --> 5.0 VDC voltage

I am asking $200 each for these reference frequency standards.
