[Elecraft] Intermittent Loss of Speaker Audio

[N4ZR]

My K3 has begun experiencing intermittent loss of speaker audio.  It 
occurs without warning, typically while I am operating but *not* in 
conjunction with events such as PTT or CW keying.  Physical connection 
to the speaker seems fine.  It also recovers spontaneously, sometimes.  
Headphone audio continues to function perfectly throughout.  Any ideas?
