I am connecting a Kenwood TS440S to an Ameritron AL-811. My question is: Do I need the amp relay cable(7 pin DIN) with the single RCA phono plug for the relay jack or do I need the cable with the double RCA phono plug for the relay and ALC jack? I am not sure if I need to use ALC for the amp to work properly. Thanks! 73 Larry K5DNA
