I am in the same "boat" as it were, having bought the K3/10. If I were considering the KPA500 then I would be looking for 40-50w driver for it. That is a 6-dB amp driven by 12w from the K3/10. That ought to be simple to make. So will K3 roll out one? Or an entrepreneur ham come up with one? Price ought to be in $125-150 bracket since no filtering is needed if used with the following KPA500.
I chose another path and bought the 300w EB-27A CCI amp that requires 18w for full output. MY total costs will be <$500 and I probably could make them for resale at $550. Stay tuned on that later comment ;-) I haven't built the EB-27A, yet, but will have results on my website when it is done later this fall/winter. 73, Ed - KL7UW ------------------------------ Message: 10 Date: Thu, 09 Sep 2010 22:10:48 -0600 From: Phil Townsend <[email protected]> Subject: Re: [Elecraft] KPA500 To: Greg <[email protected]> Cc: "[email protected]" <[email protected]> Message-ID: <[email protected]> Content-Type: text/plain; charset=utf-8 So I got me a ten watt k3... I like it... It is very good. It works. And I'm thinking of a KPA500. But to run the KPA500 I gotta get the 100 watt add-on first. Hummmm.... Is that a deal breaker? Might be. If I don't get the hundred water then I can't get fully output.!.?&-?xxx So the true cost of the kPA500 is way more... For me with just ten watts. I really only want ten watts. But when I feel the need, the need for speed (yeah I had to say it) I would like to hit the big lever marked kill and blast them out of their socks. I would like to be able to upgrade with out the interim 100 watter. Yeah, I know, i won't work but I can ask those guys who sweat solder and cash flow and you never know they just might be able to do it. To me the K2 was a total mind melt...and the K3 is beyond my wildest dreams. Quite an upgrade from the old Heathkits I used to build... No disrespect meant the hotwaters and Indians that may be still lurking.
