Hold on. Before you do, what were the voltages you measured on each side to ground? Was the cathode of D64 closer to 4.3v or ground? If the diode is good, it should drop about .7v across it, if open, there will be all 4.3v across it (in ssb). If R165 is open, you will not get the 4.3v at the emitter of TR26, rather something much closer to the supply voltage.
