[Elecraft] No Audio from speakers after FW 3.97 upgrade K3

[Dave Hachadorian]

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.
