Thanks to all for the information. I have decided to open up the 
Hercules, check the individual power supply voltages (and hopefully not 
have to get into the 9420 to adjust them), measure the individual PA 
module idling collector currents, and adjust the individual bias pots to 
get about 500 mA on each. So looking in my Hercules II manual, on page 
2-6 Figure 2-3 Top View, I see that it is going to be easy. Just take 
the top cover off to get to the power distribution board.......Too bad 
that the pictures in the manual are mislabled. The "Top View" is 
actually the bottom view.
