Disconnect amp from power, discharge and desolder PS caps from chip, then measure resistance between "3,4" and tab. If isn't close to zero, than chips are faulty (or apps note is faulty ?!).

i was trying to measure some resistors with my multimeter and was getting no reading, i found that one of my test leads was broken. i have re-tested the tabs with a new set of (working) test probes, and they are both at -15v as they should be. strangly, both amps still work when the tabs are connected. maybe when i noticed that they didnt work when the tabs were connected was a freak incedent.

sorry to waste your time.
If it aint broke, don't fix it. If it is broke, fix it.
If you can't fix it, take it apart and see how it "worked".
