When I had an A3, I built a calibrator using the Collins schematic.It was mounted in a box with an octal socket on one end and the appropriate tube socket on the top.The crystal was from Intl and it worked just fine.

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...
Thanks,
Bill N3WM
