[Elecraft] KPA500

[Edward R. Cole]

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.

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.
