Hi I am trying to wire up a mic for a Browning Mark III and am having issues finding a diagram since cb tricks seems to be down, lets just assume it is a cobra style mic, what wire would go where on the 2 pin jack ? I know they use the chassis ground to short a pin on the jack and it is keying up but I am having issues getting any modulation! Could even be a faulty tube but can anyone let me know which wire is supposed to go where on the mic jack on the radio ? Thanks
