Are you ready to face strong emotions?.. Dx Blame MKII and the Supercharged release!

is it possible to paint the heat sink in a matte color using high temperature paint Vostro? because having the aluminum polished create problems because is extremely sensitive to scratches even with you bare hands the dusty environment where I live here in Puerto Rico, also Puerto Rico is really humid too and the aluminum can get rusty I use "mother brand" that protect the metal from rust but it can be paint?

I think its been noted that the last few posts are dealing with the mating interface and not radiative thermal transfer.
Agreed thermal grease or a filler pad really works wonders, my measured best is from lightly abrading the surfaces to provide contact centers (perpendicular scoring) and remove any oxide, thorough cleaning, then immediately applying the grease or filler pad and fastening the component using a spring washer(s).
Flatness is important as is the roughness of the finish, but keep in mind that if you dont apply pressure you get a theoretical 3 point contant (metal to metal) as pressure is applied the highest point contact is flattened and now an additional contact is made, this continues as a function of the pressure, material hardness and finish.

Nice video, despite the camera audio recording does not help.

Install your speaker in a wooden panel to avoid losses..at least a wooden panel, even a cardboard panel (thick one) will reduce losses.

The reason I didn't have sound on the other channel lol

He made his own Supercharged pcboard design, almost the same as Mitchel has made and he ordered too many..he has boards left.

So, if you want boards from this multimodel amplifier contact him directly:

vargasmongo@gmail.com

Boards he has are to these amplifiers you see here:
