No stereo output on an EIIIRack for the second time

[rectape]

Just to confirm a little adjustment on the trim pot of the psu and the stere outs are 100% functionnal!

Okay....so I adjusted my trim...it was at 4.45.  Fixed three issues...however, I still have background hum on the right channel...

Any ideas?  It is faint, but it is still there for sure.  SO thrilled to have fixed the output, SCSI and HD issues..

Did you think about changing the output cable ?
Did you think about verifying the output female jack ?

If yes,

Go to disable channels, disable them all. Is the hum still there ?

If the hum is still there, shut off everything. Is it still there ? In this case change your booze, I had the same for tree days at the Odessa harbour (Ukraine), at the "kinky lobster cabaret" after a bottle of "Krasno?e heroic Kozak" (Red heroic Kozak) vodka . F... !

If not, enable channel one. Hum there ? If yes, you've got the bastard.

If not, re-disable channel one and enable channel two. Hum there ? If yes, you've got the bastard

If not, re-disable channel two and enable channel three. Hum there ? If yes, you've got the bastard

Etc...

Go till you found it.

If you found it, still verify EVERY channel (all the others), it won't hurt...

If the hum is there at every test, and even with all the channel disabled, let us know !

Will try this and get back to all.

Thanks.

hum is always present in the right/mix output jack. 

it is also present when no key is pushed or when there is no bank loaded.

I disabled all the channels and tested them both in the mix and the individual output jacks.  It is fine when going through the individual outs.

Also, there is no hum coming from the left main out.
