[Elecraft] KPA-500 fan noise

[Bill W2BLC]

I rag chew - long winded rag chew - and have never been insulted by the 
fan noises from the K3 or the KPA500. The noisiest they ever get is when 
I turn the KPA500 off - as it drains the power supply down. Certainly 
nothing like my previous tube type amp - providing over the air fan 
noise. The fan is set to NOR.

My K-Line is on a computer desk like set of shelves - open to the back 
and about 18 inches from the wall. Perhaps the spacing to the wall has 
something to do with my lack of fan noise - also providing uncluttered 
fresh air for cooling.
