That sounds interesting.  I'm familiar with the W1SL, is this 
"variation" written up anywhere? If it's been published or on the web I 
would like to see it.

I've been researching amp building for the last couple of years.  I plan 
to build an HF amp or two start, but eventually I'm more interested in 
weak signal VHF/UHF equipment.
