[Elecraft] [K3][P3] 6m Preamp and P3 on AUX Pwr

[Bob]

For that application even Radio Shack has 2.  Numbers 275-226 & 275-218.

My local NAPA store also had them in blister packs but I have not 
checked in awhile.
They were a little more in cost than Radio Shack.

A relay in this usage is a mechanical current amplifier.
