Personally, I'd buy the smallest amplifier boards possible, and use a separate power board....what else to do
The 60hz It keeps being here.
I bypass connect signal input , direct to input cap !!
But nothing change.
Does it still hum with input shorted ?
Your pcb isn't star grounded.
The input signal ground should go to power supply gnd on the pcb connector.

I gave up, use the source of this module estreo, and buy two boards mono without a source, following their advice.

The HUM is only with left input..
is good to use .66uf input cap, NFB Resist 22k , shunt resistor 890R ( 24.7x ) and 220uf Nfb cap, and 100uf Bootstrap ?
I prefer sound quality to Watts.

60 Hz?????😕😱
Santi, estás en Argentina !!!!!!
Only a correctly designed board is going to fix your problem. Messing around with resistors and capacitors will have no impact at all.
I have a new board..
Is good to use .66uf input cap, NFB Resist 85k , shunt resistor 3.3k ( 25x ) and 220uf Nfb cap, and 100uf Bootstrap ?
