[Elecraft] Subject: KPA500 Fan Noise

[Lee Hatfield Jr]

I have my KPA500 fan set to NORM,it has gone to fan speed 6 once, when doing RTTY one day,at 500 watts out for an extended time.I almost jumped out of my chair when it got to that speed. 
I lowered the input power to the amp and at 400 watts out never heard it that loud since.

I have no complaints on a fan working when I am using the amp hard.For SSB it is rare for the fan to go to speed 3. :) 

I really really like this amp, yes I would like a larger version. 
I would like 40 acres of property and better antennas too.
