T-4XC to Heathkit SB-200 operation


 

I assume this question has been answered a hundred times, but can't seem to track it down.? How are T-4XC users triggering the "Antenna Relay" on the SB-200? I was using a Kenwood TS-590 previously, and the amp has the 'soft switch' mod.

The amp connection is on the back of the AC-4.? The connectors are unobtanium but you can easily use a couple of crimp-on Molex pins.? Polarity is not important.

You can also change the connector on the AC4 to a standard RCA phono connector. ?I do it to every AC4 in my collection.
