Just using something I hadwow, that looks pretty tightly packed @mkane77g ! What are they driving? They must get warm with the cover on.
Holding your finger on the heatsink means heatsink temp less than 60 d. CI unclothed the amps and temps stabilized around 45C. I’m going to get the router out and vent the top some more. I can put a finger on the heatsinks for an indefinite period of time.
Whats s good running temperature?
That's good but it's even better if you manage to have some physical ventilation inside the enclosure.
Chimney effect with some openings at the bottom and some more openings at the top of the enclosure will prevent the temperature build up.
Below is working temperature at the top of the four electrolytic capacitors close to the large heatsinks (these are to be considered as the vulnerable part of the warm amp)
Amp at low output power (< 5W average)
operating time/temp (d. C)

I haven’t touched on sound because you all know they sound very nice. These replaced some lauded and bragged about class A amps we’ve rolled through our home. Quick, clean & detailed in a very smooth way.
Erica’s a real pleasure to do business with thanks.

Ok, thanx George.
Then the extremely cheap test speakers (3 USD from flee market) might be the limiting factor.
I was just expecting more power making the speakers distort crazy or collapse.
Right now its not much more power then the LM3886 gain clone amp I tested prior to this.
Lets do some more tests to rule out that something is not right.

Ok, tried it with a laptop. Still 3.5 headphone out to RCA. This was way louder. So all good.
So my phone is not delivering enough I guess. It won't matter since I,m not gonna use my phone as a source..
Will be feeding these from a MiniDSP2X4HD.
One module in stereo for the main fronts. And one module bridged for sub duty.
