Farhan,
Very nice design for the amplifier! I am curious, though, what it
wouldtake to boost the power to ten watts, so that the Minima could
have a 'full gallon' for SSB QRP?

I just finished a linear amp that is entirely RC-coupled except for
the power stage's output. I have built two of them and they appear to
very quite stable and clean. It uses just the 2N3904s in the chain
except for the power output stage.
The details are here http://www.hfsignals.org/index.php/RF386
It started with the a stupid question "Why can't the LM386 be used in
an RF linear?"
I am particulary curious to know what value should one pick for the
100 ohms in the Q4. I am quite kicked by the one-line band-switching
arrangement.
