My K3, of a similar vintage, had the same problem. The URL above 
describes the problem, and a permanent fix.
I didn't trust myself to change the pins on the mother board, so I used 
a temporary "bypass operation" - jumper wires around the two connectors 
to the PA. Done with 4 short wires.
Elecraft was kind enough to send me pictures of the installation. Has 
been working well for 7 years.
If the radio ever goes back to the factory, they'll change the pins for me.
