I'm working on this sound digital and founded two bad oudio output transistor
And one irf2113 chip, but after replacing all the output transistor and the irf2113
Ic, the amp powers up, but has high consumption and the clip light is on even with the gain set all the way down. Any suggestion?
Thanks in advance.

For those repair guys out there, sound digital amps can not be tested with
A 12volts 35amps power supply, I tested the amps in the customers car and it works
Fine, I then pulled back out and tested it with my 12 volts 35 amps power supply and
Again it did not worked, I'm baying a audio signal control and will it test another amps at a lower Signal level to see if it can be test it this way.

Hi guys!
The owner of the amp complained of of humming noice, I checked the amp
and founded two chips with almost the same part number, but when compare
Them they are not reading the same.
One is a TL074cn made by st, the other is a TL074cnds made by Motorola.
There is no PDF file for the Motorola for me to do the cross reference with the st.
Can some one tell me if they are the same chips?
Thanks in advance.
