I have several Trams and Browning Mark 2, 3, and 4s. Does anyone know how I can purchase the correct two- and four- conductor mike plugs for these vintage radios? I checked though the Mouser catalog but cannot identify any that would work- maybe Newark has them? I don't want to pay $10 to $15 for each one (like one guy on eBay charges). I tried the Ken's Electronics site but it doesn't show clearly the details of the plugs. Thanks much, Checkerboard
