[Elecraft] K2 speaker jack question

[Eric Ward]

OK, a possible dumb question.  K2 finished and working FB !  Audio from the headphones is fine, but no audio from the internal speaker, or from the external speaker jack on the back.  

Receive current is 220mA, so no apparent ground short, as warned against in the manual.  All the connections look good.  Has anyone encountered this before?

Could I have gotten an external speaker jack that is supposed to be wired as in the manual rev. F, rather than in the errata rev F-12 (which is the exact opposite of the original manual)?

Thanks for any help or suggestions.
