For what it's worth...I agree totally with you. I have built many amps over
the years and had my share chokes melt down or blow up. The two chokes in
series works very well. I suggest as AG6K does, if your layout allows, to
mount the second rf choke at a right angle to the first one to further
decouple the combined internal capacitance.

In a message dated 98-03-26 23:31:05 EST, you write:
<< Personally, I would use a two choke system and try to wind the second
choke with a large number of windings. Who cares if it is resonant in a
ham band, the first choke (resonant about 34 or 35 MHz) will still
function properly. Try to get a large diameter core (>1") as the
inductance is related to the square of the diameter. You'll get much
more inductance with 3 inches of windings on a 1.5" core than with 3" of
windings on a .75" core.
I hope this helps. People might think the two choke approach is goofy,
but let me tell you, it works.
