Thanks to the folks that responded so quickly. I went back to do a bit more troubleshooting and found a 60 year old mistake. The grid of the pentode section of that 6U8 was supposed to have a 220K resistor to ground. The builder of this one, who did a very good job, put a 2.2K in there instead. He must have been a CW op only. Putting in the 220K brought AM to life, even with an 8 meg screen resistor.
