[Elecraft] Elecraft Amps

[John Gaynard]

As I recall Eric stating when they first were developing the KPA800/1500
kits that some portions (high voltage boards) would be pre-assembled for
product liability/safety considerations.  There probably are a few
KPA800/1500 beta amps existing somewhere since I believe they were doing
some early field testing back in 2006 or so.  In 2005, Eric had a working
prototype of the KPA800 in his room at the Holiday Inn (QRP hotel - kind of
ironic). I believe they had a KPA800 and KPA1500 at the Hamvention in 2006.
And in 2007, the K3 took centerstage.  Time flies I guess.  Doesn't seem
like it was almost 4 years ago that the amps were shown at Dayton.

Myself, I have a K3 driving a PW-1 using a Microham MKII interface to
control PW-1 frequency/bandswitching, etc.

Since we're dreaming, how about a base model kit (500W) with the  
option to add up to two additional 500W PA modules via a power  
combiner circuit. This would allow people to configure it to their  
needs and/or budget and it would meet Phil's "something new"  
requirement. Optional: auto-tuner, optional interface (remote band  
switching, antenna management, SO2R operation, RS232 control, etc.).  
Offer a fully assembled version for those with Instant Gratification  
Syndrome, and everyone's happy!

An added benefit would be fault tolerance; the amp could continue to  
operate at reduced power in the event of failure of an individual PA  
module -- just pop out the damaged module and repair/replace it.
