I'm not sure what happened in your FW upgrade, but the U1 audio output chip is fragile. I have blown it twice now in two different radios. Both radios had the "protective" AF Output Mod installed. The chip is not replaceable in the field unless you are an expert at soldering TINY little pins, VERY close together. I'm a good solderer, and I had ordered the replacement chip, but, after looking at it, I chickened out and sent the DSP boards to the factory for repair.
Elecraft, the speaker amp needs to be more robust.
