***UPDATE:  New Adapter Kit for the Drake 2-Pin VOX Connector***

03 May 2014:  I am now pleased to announce availability of the new RA-VOX2RCA adapter kit from Paul Kraemer, K0UYA.  The RA-VOX2RCA is an adapter kit to allow conversion of the Drake 2-pin relay connector used on AC-4 power supplies and L-4 series linear amplifiers to a standard RCA phono jack to facilitate interconnection with a traditional RCA patch cord.  The conversion also allows for easy connection of the AC-4 keying circuit to other linear amplifiers that use a standard RCA jack for connection of the keying line.  The kit comes with a new RCA jack, lock washer, ground lug and adapter plate.  They are available in the Drake products section.  I will also have them at Dayton.  73, Jeff  W8CQ
