[Elecraft] KPA100 Temp/Fan

[Jim Stoneback]

Wow!  Thanks for all your replies.  I think I'll take the advice offered by 
several responders and set the fan for 'hi/lo' and stop worrying.  I can 
live with the noise using headphones much of the time anyway.  Just thought 
it was odd.  Next time I open the rig up, I'll recheck the bias to the 
finals - just to be sure.

73,

Jim
