[Elecraft] Speaker problem

[David Wilburn]

Copy of builders alert message.

We have a new Builder Alert, covering the wiring of the new type (RoHS 
compliant) of K2 speaker jack.

Read about it on our website at:

 
http://www.elecraft.com/Apps/Builder's%20Alert%20New%20K2%20Speaker%20Jack%20Rev%20A.pdf

This Alert applies to K2 kits purchased since August, 2006.  If you have 
found that your external speaker doesn't work, please read this Alert. 
No parts need to be replaced, just some very minor rewiring work needs 
to be done to the external speaker jack.  This change is not covered in 
the manual, but is in the new Errata (Rev F-10) also available on our 
website in the "Manuals and Downloads" section.
