I got another 1 of theese in for repair.. This board is the REV E


As soon as i connect a speaker to the left channel the amp draws 20 amps of cirrent..

Any ideas??

Is the bias all the way up? That might do it.

Bias pot is fully counter-clockwise

Is there DC voltage on the speaker terminals of the left channel?

[mike49504]

Yes 28 volts is on the output for the left channel but outputs test good

[Perry Babin]

That's why it's drawing 20 amps when you connect the speaker.

What have you done to the amp up to this point?

[mike49504]

Replaced D3 (1n4003) and fixed the broken trace that goes to the diode is all ive done..
