NE5532AN the following pins have signal on them

Post the IC number (U1, U2, U3...) and the output pins of each one with signal on them.

[mike49504]

U2
PINS 2,3,5,6 have signal on them Pins 2,6 the signal is clipped

U1 pins 2,3,5,6 have signal on them

Both op-amps have + - 17 volts on them and the rest of the pins are at 0

Perry,

I played around again with one of the switches and i now have signal where r30-32 meet and r33-34 meet

One of the driver boards is getting warm.

Also a tip 102 and 107 in the power supply section are getting warm also at idle maybe the regulators?

[Perry Babin]

Q43 and 50 are the regulators.

Do you have audio on the formerly dead channel?

[mike49504]

The one channel is still dead and the other has Dc on it

[Perry Babin]

For the dead channel, do you have audio on at least one solder pad for the driver board?

[mike49504]

Back to this amp again I found a bad op amp and replaced it I of the outputs has 20 volts of Dc on it. I checked the outputs none read shorted but wondering if they are leaking hers what i came up with.

Hope you can make out all this Do any appear to be leaking/BAD?

[Perry Babin]

You can't determine if they're leaking unless they're out of the circuit.

[mike49504]

They are all out of the amp I tested them 3 times out of the amp and thats what i came up with. All the readings i posted were taken with them out of the amp Thats why i was asking the readings look strange to me
