[Elecraft] No output - internal spkr - K2/100

[Dohn]

Howdy .. My real problem is that when there are no headphones plugged into
the front and nothing hooked to the "ext spkr" in the back I'm not getting
anything through the onboard spkr in my K2/100.  This is true of the spkr in
the QRP lid as well when swapped out.  This happened suddenly last evening.
The internal speaker was working fine, and then I noticed it wasn't working
later in the evening.

 

The "ext spkr" is producing no audio now.  This is true of the KPA top and
the QRP top.  The lack of audio in the internal speaker  and the "ext spkr"
jack in the back are tied together I'm sure.  I get a nice waterfall in say
HanScope when the audio is taken from the headphone jack in the front of the
K2/100.  If I then switch back to the "ext spkr" in the rear there is no
sign of audio present in the HamScope waterfall. No audio at the internal
speaker on the way up to plug into the rear ext spkr jack either. 

 

Any ideas why my ext spkr jack in the back of my KPA100 would just stop
working?  I plugged the QRP top back on with the speaker hooked up.  The
same thing so it's not the jack itself. No audio through the internal
speaker or "ext spkr" jack but the headphones at the headphone jack in the
front works fine.

 

Thank you in advance for any ideas you might have.
