[Elecraft] KPA-1500 Fan Noise - YouTube ?

[Bill Stravinsky]

You pretty much hit the nail on the head about solid state amps.  As they say there's no free lunch.  Solid state has made great strides in high power ampsbut its still solid state and a p/n junction or some form thereof.  1500 watts of heat in those junctions has to be cooled down or it won't be long before it needsnew parts.
Depending on your operating habits (contesting, casual, or whatever) there will be varying degrees of fan noise.  The higher the duty cycle the higher thefan requirements.  Pick your poison, a small light weight amp easy to move around or one you need a fork lift to pick up.  I prefer tube amps for a few reasonsand have the Acom 2000a (and an Alpha 89 that now sits in the living room temporarily) but I'm still glad I got the kpa1500 at least so far.
The kpa sits nicely on top of the Acom without causing the table they sit on to crash to the floor in pieces, hi.  I'm surprised nobody has made a you tube ofthe amp in operation actually.  But there are only just over 200 of the new amps out there.  Good luck with your investigation, Rich.

 This fan noise issue has me concerned to the point that I’m considering cancelling my order.

While the amp won’t be on my operating desk, it will be on a rack next to my operating desk.  Remoting the amp is not an option. Quite frankly I have no interest in remoting the amp.

Is there anyone out there that has a KPA-1500 willing to post a YouTube video so we can hear the fan in action and judge the noise for ourselves?

>From the research I’ve done it appears that if you want a solid state amp, regardless of make, you need to be prepared for fan noise.

Thanks
