Those old adapters with a 1/4" key plug on one end and two 1/4" key sockets on the other, that used to let you plug two 1/4" key plugs into one 1/4" key socket on the rig are getting hard to find. Does anyone have one or more to spare, or know a source? Any advice appreciated! Much tks and vy 73 to all!! Jan N0JR
