Pod XT Live! with toasted op-amp for headphones... could use a little guidance

[OneTwo3]

So I burnt the chip playing the thing straight into a 4x10 cab out of the headphone jack...
Never do that !

The op-amp for the left side of the headphone put put is toast, and there is little chance of repairing that since the board itself is pretty burned underneath it too.

What I would like to do however, is complete the circuit so that the thing will do stereo chorus/delays again.

I can listen to it in mono from the headphone jack, and it works okay every other way except I can use the L/MONO, or the right 1/4' output for guitar amps and either one works, but only in mono.

I think that if I complete the left headphone circuit it'll be back to normal again, but i am not schooled enough to know exactly what to do.

There are three leads that were under the op-amp that I can jumper, and I have the schematic.

Should I leave well enough alone or is stereo output possible with a little surgery?
The op-amp is removed from the board, it is labeled U11 on the schematic.

Any pointers will be greatly appreciated!

The headphones amps U9 and U11 are the TL084.
Good luck.

Yeah, but the pads for it are burned off.
All I have left is the eyelets feeding the pads from underneath...board got crisped some.

I see three circles of metal under the TL084 that I could jumper one way or another to bypass the TL084, and complete it's circuit hopefully.

It's a busy schematic with all the auto sensing to detect headphones, I think it's confused now without the chip in there.

You could try a 'dead bug' repair.
Identify where all of the opamp leads should go.
Glue the opamp to the board, upside down (dead bug).
Then reroute the wires from the opamp to where they should go.

I'm a bit confused, you need a stereo amp to get stereo fx. You won't hear the phasing difference between L & R out unless you have them both connected to amps (or you have a stereo headphone out which you no longer have).
When you plugged into the cab, were you using a y-cable or something?

Yeah exactly, when I connect to two amps, only one gets an input. Either one gets an input if I unplug the other cord, and I think normally only L/MONO puts out when one cord is in the Pod.

Not trying to get stereo headphones, but would like to restore the stereo output for use with two power amps.

I like the dead bug Idea, thanks- it would ease my mind knowing the currents were proper and all.
That's what I'll try to do, but it is almost like neurosurgery this stuff is so small these days.

If the print and pads are damaged this is a problem.

Try to mount all circuit on the DIP package and connect this hybrid circuit to the print (previously remove all duplicating details from the print).

Here is schematic of the headphone amplifier:

Ah, yes I see that is a good idea... taking the dead bug concept to the next level.
I like the idea because I know the added confusion of an upside down backwards circuit ( dead bug ) is no longer an added confusion while working out the schem, Excellent thank you,
Thanks for the Schem too, I had it already but not on one page all by itself, so I will use yours instead.
Thanks!
