[Elecraft] no audio output: K1

[Don Wilhelm]

Steve,
I recently repaired a K1 with the same problem (no audio, but sidetone) and
discovered that it was an unsoldered connection at the RF board/Front panel
connector.

Not to say your problem is the same, but just saying 'check everything twice
and a third time if required and don't overlook the easy stuff'
