&& Nice amp Bill. Are you sure it only runs the legal limit ? How many
8877's are inside? If that 4:1 balun on your X-7 ever gives you trbl,
Jay at Array solutions has the real deal for 4:1 baluns. 5/10/20 rated.
They also work good on the old KLM yagi's.

&& I have a rack mount Bird, and also a CD, model 83000, and also 2 x AS
couplers, and 4 x AS rack mounted displays.. + 8 x slugs. My 4 x drake
amps
all have 0-3 kw pep meter's built into em. I have a W-4 as well.

&& say what? It ends up back at the cathode, completing the loop, Fig 22
in any orr book. 'Untuned cathode circuit grnd return'. Cold ends of tune
+ load
caps... along the chassis, down the braid of coax to exciter... up through
load cap
of xcvr... down the hot side of the coax..... back to coupling cap... which
bonds to
cathode, completing the loop. We are talking about the 210 deg pulses
from the
anode... which are aprx 3 x the dc plate current. [ IF a PI tuned input is
used, the C2
cap of the tuned input, has to handle these pulses.. PLUS normal current
from the
xcvr. ]
&& Bill, it appears you have missed the basic concept of how a GG amp
works.
Perhaps a review of Ch 15 is in order. RF just doesn't.. ..'end up in mid
air'

But then you came.

&&& Neither. No pix on this reflector, too bad. I did learn something
here
though. My HV caps are the eq of 1.2 sticks of dynamite.. and not to be
trifled
with.

&& depth of penetration is .05mm on 160m... and .01mm on 10m. Sez so, in
Bings
RF software package.
There are a LOT of holes surrounding the tube /socket. Has to be... to get
the pressurized
air from below chassis.. to above chassis.

&&& stupid, not well thought out... rules. Actually, I think they are
more
like 'guidelines'. How much ERP do you have ? Hope it's not more
than 1.5 kw.

&& actually, I could use the $2k. The new 6' x 6' x 9' block of 6000
psi concrete
will cost that much. Do you think you could get it to me b4 the 15th of
next month?
later... Jim VE7RF
