I will continue to supply crystals for Collins rigs... Including some of the oddball ones that are hard to find like 15.3775 MHz 15.6275 MHz 16.0275 MHz etc. Plus we have the WARC band crystals for the S-line and KWM2 radios in good supply, along with the regular ham band should one ever fail. Prices generally are $12 to $24 each. All the best - Bry Carling, AF4K
