I just finished my ACA Mini build. I brought the amp into the room it will be used to acclimate to the ambient temperature. I set up two meters. I set VO at 11.5v and VB at 250mV....Then I let it sit for 15 minutes. VO dropped to 11.47 and VB increased to 308mV......Is this normal and now I should tweek it to 11.5v and 300mV?
What happens this summer when the room is 20 degrees warmer?
What is the ramification if these numbers creep up or down? Any danger to the speakers?

all settings in temperature equilibrium
simple as that ....... probably your initial settings was while heatsinks not fully warm

Just take your time and tweak up or down in small steps. When you're done it
will drift a bit with ambient temperature, but not a lot.

Thank You!...It's done and playing right now. Amazing little amplifier! I bought it just to have something to do.....I like building HiFi gear....But I never really thought I'd be using it in my main listening room. I'm here to tell you that I could live with this little amp.....But then again, I have a First Watt F5v2 Turbo that owns my ears! Thanks for what you do....With the ACA Mini, Ya dun did it again!
