I recently purchased an ACOM 1000 Linear Amplifier. I received the amplifier, unfortunately DX Engineering has backordered the essential keying cable for a FTDX1200 into November, with no assurance they will even ship it then! Can anyone help me with an alternative source for this cable or has one they are willing to sell? I had a heart attack last Saturday and would really love to at least use this amplifier once before I have a valve replacement in October. Any help is truly appreciated. Thanks!
