[Elecraft] KPA1500 Fan Noise

[John Perlick]

Every amplifier has some level of fan noise.  My new KPA1500 is seriously quieter than my former Expert 2KFA.  

My Henry 2K Ultra fans were so loud that I couldn't keep it in the radio room.  Luckily I had the remote version. 

My Harris RF-3230 (all solid state) had 8 six-inch muffin fans!  It sounded like a DC-9 warming up for a takeoff.  I was two rooms away from the shack and I could still hear those fans!

I run my KPA1500 at 1500 Watts SSB/CW and I have never heard the fans go past setting #2.  If you want to run 1500 Watts of RTTY or AM, then expect the fans to be running hard to keep the amp cool.  If you want a quieter shack, put the amp in another room.
