[Boatanchors] Collins 75A3 crystal calibrator 8R-1

[Glen Zook]

The same calibrator was used in the 75A-2.  If you cannot find one, the circuit is very simple and a suitable replacement could easily be home brewed that looks just like the original.

Guys,
I'm trying to find out more information on the 75A3 - 8R-1 crystal calibrator. I can only imagine they are very scarce..wondering what they are selling for if you do find one...
