Two eBay crystals showed up today.
Picked one at random, soldered into counter and changed a couple other questionable parts while I had the iron hot...
Bingo! Operation has been restored.
Threw the counter inline with a transceiver and netted the trimmer cap as the unit read the transceiver's frequency. A break for dinner then buttoned up the case and it's done. Thanks for everyone's suggestions and junk-box inspections - luckily, I was able to get this thing back into working order cheap.
Sweet success! Nice work!
