Does anyone know the proper spec for the Hercules II PA bias. It has
MRF458 devices.
I read somewhere it needs to be 500 ma per pair of transistors which is
consistent with radio PAs that use these.
Amp I just acquired has PA bias set at 1.5 amps per pair. This amp
looks unmolested as screws show no screwdriver marks. Is that bias of
1.5A factory set?
Thanks
