The PA1000 by Juma looks even better:

I am a very satisfied owner of both a K3 ( with a KPA 500 and KAT 500) and a
KX3. I decided to order and build a PA-100D linear from JUMA Radio as a surface
mount kit. It is a very compact linear which will produce up to 150 watts out
with between 3 and 10 watts drive. It is well filtered and from tests I have
done has a very clean output. Using my KX3 As a 2 tone generator I measured
2nd order distortion of better then -28 db. The JUMA engineers measured greater
then -33 db with 90 watts out using calibrated lab equipment. With the new
firmware it will work with the rs232 from the KX3 and other rigs so will select
the proper output filter (switch bands) or you can use RF detect or manually
select the band. It is crammed with safety interlocks and protection
circuitry. If I want to run more power I use the output of the JUMA linear to
drive my Heathkit SB 220. I have received excellent reports from many stations,
many with K3/P3 and Flex Radios that could see my
output. It
does use a cooling fan on the heat sink but is very quiet. Running PSK31
using the linear with 30 watts out the fan never got to full speed.
This kit is 450 euros ($600.00 USD) so it's not cheap. Is it as good as the new
Elecraft KXPA 100? Probably not and it doesn't cover 6 meters. But if you like
a challenge and want a good linear to boot then check outWWW.JUMARADIO.COM. I
have no relationship with JUMA but enjoy the linear.

Better check the writeup. It says that the amp will not work with the Flex or
KX3.

Why spend more when you could spend less?

QRP is looking better, I looked at the out the door price of the Elecraft
100W amp with tuner. Ouch! around $1300.00 bucks with tax and shipping I
was imagining around $600.00 I'm way out of step. Yikes! a hundred watt KX3
is close to the price of a 100 watt K3.
