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
