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

[w5jo at brightok.net]

And International Crystal stocks the 100 Kc. crystal for it at a nominal 
price the last I checked a couple of years back.

I built one out of a very small Bud box but check the measurements to be 
sure you get the right box when you order.

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...
