is it a 120Hz or 60Hz?
I have 0.25mVrms @ 100Hz (in EU) on my latest 801A direct coupled amplifier ... just finished yesterday (well ... I am missing the definitive 4pin sockets actually). I love direct coupled amps
:-)
Follow Ups:
in my fathers amp I think little bit of both 60 and 120 cycle.
no direct couple for me as I am trying to preserve "dynamic transconductance" and this can only be done with plate choke/grid choke RC couple system this combined with lower power supply DCR works is what I am doing
