thanks Nomad. I checked the 2 bias posts. Same full voltage as at the front lead of TR41. When you key radio it drops to 6.2 at TR41 and at the two bias posts but still no power out. So not the mode selector likely? What is it then?? Mystery.

voltage at driver: ground, 290 millivolts (AM transmit), 1.0 v
Voltage at final: ground, 6.2v , 0.9.
Almost seems to be the driver? Though I replaced it couple days ago. Maybe I toasted it again? I have a couple more on order.
