I’m working on a Taramps 8K the driver ic’s for the outputs are SI8244BB
I’ve included a data sheet for these .
Wondering if these voltages appear correct or am I missing some voltages ?
Amp will power up but no audio
Pin 1:3.55
Pin 2:0.00
Pin 3:5.00
Pin 4:0.00
Pin 5:0.00
Pin 6:1.19
Pin 7:0.00
Pin 8:5.00
Pin 9:0.00
Pin 10:0.00
Pin 11:12.80
Pin 12:0.00
Pin 13:0.00
Pin 14:10.33
Pin 15:10.33
Pin 16:12.39

I haven’t catalogued the voltages on those ICs, so I can’t say for sure about the voltages. I usually use my oscilloscope to check the drive at the output mosfets. If they look equal on both sides then I move on from there and I’m reasonably certain the the driver IC is working properly.
You could have a broken inductor winding, or a problem in the preamp section. Could be something as simple as a broken connection at the board on your RCA inputs or missing regulated voltage to the op amps or a defective op amp.
