Saving that $110 plus postage is one advantage of being a "solder jockey" - but I've never managed to damage one of those IC's with a brief signal no matter how loud. They saturate, keeping any voltage spikes inside the limits they can withstand.
What will kill one, IMX, is a sustained saturated signal (for several minutes) that eventually causes the chip to overheat from excessive power dissipation. Big Bear Lake ought to be beautiful this time of the year, Dave. (I was raised in Redlands, down below you in the San Bernardino Valley.) But so is the central Oregon coast this time of the year :-) 73, Ron AC7AC -----Original Message----- 2. Never use the speaker amp with AGC turned off. It takes just one dit from a loud signal to destroy the delicate speaker amplifier IC. That will require a $110 factory repair, plus postage.
