Phonic 1062 mixer amp,2006
Threshold and then proportional but as difficult to find what that
threshold is and what initial proportional voltage, looks like I'll have
to delve into the smps, at least only 6 sc hold it in place. As amp is
never used for "quiet" use no problem with elevating the startup voltage
to 8V or so, if I can determine the circuit enough to find where to
change a value, no preset seen
