Well I found what was causing the voltage problems...after checking all around the system I recalled that I had replaced a leaded 2N3904 with a 2N2222A for Q90 since they are equivalent, right? Well, yes, but the pin outs are reversed and even further from the original pin layout of the original SMD 3904. Correcting that mistake now gives correct voltages on all transmit transistors from Q90 on through the finals.
However, still no power out. It is oscillating on frequency and sounds fine...just no measurable power. Raj, I do get blocking action on C80, so can I just bridge it with a leaded cap of the appropriate value? I haven't touched RV1, but maybe I just swing that through its range as well. After spending literally hours on it this afternoon, though, I am going to take a break before moving forward now.
