Hello...

Thanks for the responses I got to my post sent quite a while ago (see below)-- about my Omni VI with no power out.  A local ham, W3GMS, suggested that I start by checking the drivers and finals out carefully.

So, I "gave in" and opened up the PA enclosure again and checked voltages and the current draw.  The transistors all seemed to be biased correctly, but the drivers didn't draw any current.  Bottom line:  I replaced the driver transistors (2SC1969) and the problem was solved.

I was very fortunate that it was a problem easily detected with simple equipment, and that they are easy transistors to remove and replace.
A happy ending, so far ;-).

Tnx & 73,
Jim, AF3Z
