[Elecraft] Need advice

[Lynn Lamb, W4NL]

Maybe a problem.... maybe not!

The K3 works fine except the speaker audio has gone away.  No external 
speaker and when unplugged there is no K3 speaker audio either.  The 
headphones work fine as every other part of the K3 does.  I've not removed 
the top or in any way upset anything.  I've checked every control and menu 
settings although I've not messed with them.  One minute it had audio from 
the speaker and the next none.  Any ideas before I call Elecraft?

Thanks....  Lynn W4NL
