[Elecraft] KX2/3 Amplifiers

[Tom Francis, W1TEF]

Greetings,

I'm looking for a little practical advice about linear amplification for 
the KX2/3 (I have both).

Hardrock-50 or KXPA100.

Essentially, it would be used mobile, although taking it out the car and 
using it portable is
possible.

So any information from users of these two amps will be greatly 
appreciated.  Also, as the
Hardrock 50 is a kit, how hard is it to build for something with finger 
nephropathy?

Thanks for any info.

Very best regards,
