KPA500 fan

[Bill-3]

On the subject of quieter fans, any thoughts on a quieter fan for the
amp? I do a lot of AM and a quieter fan would be nice - else the amp
will get relocated to a different location in the shack.

I think about the only real solution for the fan noise on the KPA500 is to remote it.

Bill,

Have you considered (or already done) setting the minimum fan speed to 2 (or
3)? Doing this helps delay the onset of higher fan speeds. Of course, long
duration AM transmissions this may not help, but I have notice it help on
lower duty-cycle modes.

73,

Bruce, N1RX
