Thanks in advance to those who may respond. I'm putting an Adcom GFA-5400 in my theater setup as the fronts driving Thiel 3.5's with the bass module and I've adjusted the DC offset to nigh onto 0.0 and am in the process of tweaking the bias. I've upped it to 0.053+/- and the temp of the heat sink is about 42C. Nelson Pass in a post biased his by touch but he didn't state a preferred voltage. Has there been an accepted bias voltage maximum for this amp? As I'm sitting here, the v has gone to 0.055 and the temp to 44C. Does Bias tend to run away with increased temps?
Best to hear Pa, what he says, taking in account specifics of heatsinking and power supply
I can comment only looking at schematic, and that's not real life context
