I had removed them earlier to double check where the Trace was going. One of them on the bottom of it was metal flake it was the one that's located right beside the resistor that melted off the board earlier.
Not too shore. It arrived here like that but underneath each capacitor was clean and no corrosion on the pads. I set my scope to capacitance but when I go to check it doesn't show anything.
With no load I still have 22.35 DC volt. With 1.5 amp the amplifer is pullilng.. with a 4 ohms load(subwoofer coil) fans turn off. Amp only pulls .9 amps and voltage of speaker terminal goes to + 40mv. It's Chang's form .40 to .32 mv the coil is cold to the touch
I can pick some opt coupler up tomorrow along with new caps. I'm down the street from from mouser. Just to clarify the opt collector are U406 on the top it say A3120
