[Amps] Solid State bias adjust?

[Philip de Cadenet]

I have a Metron amp which has but a single pre-set to adjust the bias 
for all 8 devices. Is this shared in such amps as the Henry's, SGC and 
Ten Tec Hercules or do they have a single pre-set for each pair of 
transistors?

If you use a properly matched set of output devices am I right in 
thinking there would be no advantage in having separate pots per output 
pair?

Thanks.
