The only surefire way I know of to piss off an 843 is to power it up from a slowly rising power supply. You see this with bench supplies when you have the current limiter turned down too far, so that it stays in current limiting mode for several seconds while the rail caps on an amp charge up. Except that with an 843, current limiting stays on forever in this situation, because the chip drains a lot of power in this state.
There are other ways, but I've never gotten down to a science how to reproduce it.
