Bill (and others needing crystals),
1. I do have one from an R-390 (not A) oscillator unit. Fair Radio was
selling these for $20 near their end, plus shipping. Payment by check.
2. But other crystals will fail from time to time. So I went on
Digikey.com... They have a bunch of crystals, mostly SMD types. These could
be put inside the original holder. Even MHz are pretty common there. What
about drive levels? Is a tube osc too much drive for this little thing?
There is a datasheet for it on this page. So this approach might help others
in the future.
Here is one by CTS for $0.72:

So this approach might help others in the future.

Happy July 4th!
Does anyone have a donor crystal bank with a 14mHz crystal they
would be willing to part with? Please advise with price + shipping
to my QTH (below).
