On the supply side I used two toroidal transformers of 400 watts, each with two windings of 18 volts. So I won two individual power supply, one for each channel. On the filter I used 8pcs of 33000 uf capacitors rated at 25 volts.
As heatsink for the power resistors I used 4 pieces of cable modem lancity brand, cool pretty well and looks good .
The sound quality is briliant!
The only 5 watts get enough power for a 5mx4m room with a pair of speakers with high sensitivity. I listen on Focal 807V speakers with sensitivity of 92 dB.

NICE BUILD....WOW...BUT PSU ISN'T OVERKILL?.....
The PSU is spot on

Nice work. I like the fet - heatsink sandwich.
thanks, it was necessary to dissipate as much heat as posible.
In a cold winter is nice to listen the music, as near a fireplace
