That chip is fragile. I've blown it twice, just with excessively loud audio. (AGC OFF) I'm a fairly good solderer, and I bought a replacement IC here: http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=LM4950TS-ND I was able to remove the old chip by cutting all the leads, and removing them one by one, but when I looked at the tiny pads on the circuit board, I chickened out. I couldn't see any way to solder those pins to the pads without shorting them to each other. They are EXTREMELY close together. I ended up sending the DSP Board back to Elecraft for repair.
