But if I leave them down for a while, it might take 4 or 5 hours for them to get good.

Yes, it is exactly it. It is OK during the winter - sometimes run the power amps for days, but during the summer to run all 12 Milq’s channels for 4-5 hours just to have a decent listening session after a few days of break is kind of sad thing to do. For 5 hours Milq hits the room that I can cook pizza right in the Micro-Seiki platter.
I wonder if it possible to identify and isolate the cause of the problem and to apply a narrow targeted cure. For instance if it is about getting a right temperate in the power capacitors then would it possible to wind heating coils along them with a thermostat and as soon the amp starts and to heat the caps very fast to the default “best sounding temperature”. If it is about the agitating the dialectic then it might be possible to give to the caps the very short “shaking stress”. Perhaps it might be done by a period of operation with removing rectifiers and to driving the caps with AC. Frankly, in such a big and complex amp as 12-ch Milq is I would not mind to have a switch that would temporary activate some like of local burn-in oscillator that would “age” the caps very fast. I wonder if anyone did any research or have any solutions in the felid.
