I’m wondering if anyone else has had this problem?  When I shut down the KPA500 
from the front panel the cooling fan turns on and instead of shutting down it 
continues to run until I turn the power off on the rear panel.  When I turn the 
 back panel power switch on again the fan immediately comes on and never stops 
until the back panel switch is turned off.  I originally had this problem 3 
years ago and Elecraft had me install a SMT bypass capacitor on the back of the 
front panel board that I thought had taken care of the problem (It did for 
several years).  I have reloaded firmware, done a full reset, etc. but the 
problem persists.  The amp work perfectly other than this glitch.  Any help is 
appreciated.

Thanks, Todd
