[Milsurplus] relays

[telegrapher at q.com]

Does the 390 series radio use 6.3Vac relays? Have a couple that came out of a box of 390 parts, metal sealed with one spdt and one spst type contacts Not very big and in a gray metal fixture. Seems to me when i played with one years and years ago that i could operate one or more of the controls and hear a relay click. That's as far as i got into it. Think almost 45 years back. What radio?
