This listing is for (1) RL Drake Crystal 36.6 MHz for 25.5 to 26.0 MHz Range. It is Used and in excellent condition. This Crystal was removed from a working radio and was briefly checked before it was removed. I simply can not test each crystal but I will offer a satisfaction or money back Guarantee (including the shipping cost) if you have a problem with your used crystal. It is the larger type crystal found in most RL Drake Radios like the 2B, T4X-C, R4-C, TR-4, and others.The crystal you will receive may be different than the one pictured but will be in similar condition.It is expensive to order a new crystal and it takes several weeks to receive them so this is your chance to pick one up at a reasonable price for your fine Drake Radio!
