[Elecraft] Now fixed - new question Re: K3 - Hi Cur and no speakeroutput

[Dave Hachadorian]

Congratulations on replacing that IC! I was too chicken to try 
it. I'd like to see the advice you got for replacing it.

The speaker amp is fragile. I have blown it twice by running with 
AGC off, AF limiter threshold high, and tuning across a very loud 
signal.  It is reasonable that a high-Z load could be a problem, 
but I don't know for sure.
