A nice Surplus Receiver from 20-28 MHz FM. I got it from a friend as broken part. The 24V vibrator and a thermal resistor (tube) was broken. I opens the vibrator and clean the contacts. After the change of the thermal resistor for the heading voltage, it works again.
This is a Part of radio sets AN/GRC-3, AN/VRC-16 & AN/VRC-20. It was use in the Vietnam War.
20 .. 28 MHz
Mass + weights: 178 x 229 x 305 mm, 11.35 kg
Now I search the connectors and a speaker.
Here you can see a video with a test:
