On this amp I bet 240 volts of rail on only half of the outputs .
The other half of the outputs have 0 volts on them .
Is this normal for these amps does anyone know ?

I have regulated voltages on the opamps .
These amps use IR2110 driver ic’s on 1 ic I get 4 volts on pins 1 and the other ic I get 0 volts on pin 1 wondering if this is normal or I have a problem somewhere ?
The map had shorted outputs and I changed them out with original part numbers and switched out the driver ic on the bank of outputs that failed the other ic is still original .
Amp powers up and idles fine produces regulated and rail voltages but I get no audio at all

Can anyone tell me if these are switching diodes or regular diodes?
They connect between the LO pin of the IR25607S driver IC and the gate leg of the outputs IRFP4868.
The other diode connects between the HO pin of the driver IC to the gate leg Of the other outputs .
So they are being used for the high and low side drive .
