[Elecraft] KPA1500 fan noise concern

[Ralph Parker]

I'm on the list for a '1500, expected sometime in August (maybe). 
However, I'm getting concerned about the reported high fan noise level.
I currently have a '500, and following a suggestion a year or two ago, 
I've turned the fans around 'backwards' and they seem to be quieter in 
this configuration. I would give the '500 a "quiet" in the noise 
department. Temperature does not seem to be an issue.

In addition, I have an Acom 1000, which is also a quiet amp - fan as 
well as relays. Hard to hear it in operation (but the 3 minute warmup 
usually seems like three hours. :-)

I ordered the '1500 In the quest to be a couple of instant db louder, 
but if I don't hear some resolution of the noise 'problem', I'm going to 
put the order on hold until it is solved. I do have many headsets which 
I usually wear, including the Bose QC15 noise cancelling model, but I'd 
hate to be FORCED into using them.

A concerned citizen.
