[R-390] 200KC calibration crystal?

[Bob Camp]

Hi

I would be careful that you are getting the right crystal. According  
to the guys at Collins that crystal was tough for them to get even  
back when the R-390A was a new design.

You might ask them what the price for 5 or 10 crystals would be. It  
may be surprisingly low compared to 1 piece. I'd bet there are  
several people on the list looking for the 200KC crystals.
