[Hallicrafters] SX-62 500kHz crystal

[Julian Bunn]

The crystal marker in my SX62 wasn't working. After substituting a 
crystal of different
resonant frequency, and finding that the 6C4-based oscillator worked, I 
pinned it
down to the installed crystal itself being faulty.

I carefully took the case off it, and inside found that one of the 
contacts had separated
from the thin sliver of crystal. It was very fiddly, but I managed to 
resolder it back on.
However, the crystal still doesn't work.

Anybody have any advice: is this likely to be repairable, or do I need 
to find another
crystal? If the latter, where would I find a 500kHz crystal for sale?

Thanks!
