Does anyone know what the correct PA bias is on the Hercules II? The 
transistors are MRF458 and I saw somewhere a reading of 500 MA per each pair of 

What concerns me is I have a Herc II I got from the original owner who said it 
was never opened or repaired and my bias is 1.5 amps per pair.  It makes me 
think that might be the factory setting. I checked the bias board for problems 
but none and each pair is adj to almost exactly 1,5 amps.
