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

[Bry Carling]

We currently have 4 of the 100 kHz crystals (tall hc13u) as used in Collins and others.

They don't last long here!


We also carry the special 200 kHz crystals specified for some of the other S-line rigs.

 I think it is the 51S1 that uses those.  I don't recommend trying a home made calibrator as some have done.

AF4K Crystals also has the 100 kHz crystals in stock most of the time.


E-mail me off the list to arrange purchase.

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...
