The article by W6RF in Com Quart was technically excellent,
except for the attack time constant error in the auto bias system.
I do not think amplifiers should be designed that are driven
by a few watts unless you own an exciter that ONLY puts out a few
watts. Low drive power requirements cause many needless problems
for operators. (The problem is easily cured with the addition of
one extra low cost resistor, as I pointed out.)
Before I can answer any questions about any other article, I'd have
to know what you'd want to build. W6FR's was the best one on grid
driven PA's in a long while, since that was the topic.
Is there a lot of interest in a detailed article that describes WHY
certain parts are chosen? If so, what tubes and configuration would
be the most popular?
Perhaps Ian could suggest something from overseas, he is a very
thoughtful person when it comes to good designs and a technical
editor.
73, Tom W8JI
