[Elecraft] KPA500 Buzz SOLVED

[n5ge at n5ge.com]

I had a loud fan in my KPA500.

I contacted Gary and he had them send me a new fan and all was well.

Merry Christmas to all of the folks at Elecraft.

Excellent customer service all the way around!

"If somebody has a bad heart, 
they can plug this jack in at 
night as they go to bed and it 
will monitor their heart 
throughout the night. And the 
next morning, when they wake up 
dead, there'll be a record."

>My KPA500 #274 worked fine with the yellow wire installed, but the voltage was a bit low (56-year old house) and output on 6M was also a tad low.  I wired it for 220v.  Since I use it for meteor scatter on 6m, I really wanted full output.  But when I switched to the red wire, I got a terrible buzz.  I don't mean a slight buzz, I mean a buzz on the order of an arc welder running at full tilt.  A buzz that was louder than when the pole pig across the street caught fire.  A buzz far too loud to be tolerated in a nice, quiet, Elecraft-equipped shack.
