Hi ,
i just fixed my eci-4 with schorted output transistors.
All the work is done and i need some help adjusting it.
Everithing measures fine when starting up with variac.
I set DC offset to 0V in both channels .
then biassing is the problem.
It seems i can't get the bias current low enough.
Do i set bias at 13mV when the amp is cold?
All info on this amp is welcome
thans
