[AMRadio] Todays Toy - Elmac PS-2V

The original relay probably pooped out and was substituted with a six volt 
DC relay.  The extra connector on the end of the cable is most likely for 
the mobile receiver or front end converter.  I got a bad feeling that the AF 
54 67 and 68 will be going up in price soon due to the demand for quality 
plate modulated stuff.
Thanks for the FB pic's JT
