Actually, a very nicely built 6 and 2 meter amplifier.

I don't see any strip line. Best I'd give it is "nice front panel."

Well, you look at the copper strap connecting the 6 meter tank to the tubes.
Those.are called "strip lines" and are what resonates the tank on 2 meters.

Now to replace those 4CX250s with 3CX800s or a pair of 4CX*** in that
range :-)). I'm using a single 3CX800 on 2-meters. It's just the
thing for WAR (Worked all Repeaters) :-)) and no in case anyone took
me serious, it's for SSB and CW although I keep telling the locals
it's for packet.

I see the tuned lines, but they are not strip lines.

See http://en.wikipedia.org/wiki/Stripline

Or an ARRL Handbook, or........

Nah! Those are simply hi-Q, low inductance, inductors that happen to be made
of copper strapping.

Strip line is a transmission line that is made by putting a strip of metal between
two ground planes. It's impedance is determined by the width of the strip, the
spacing between the ground planes, and the dielectric constant of the material
between the ground planes.

Strip line used to be used quite a bit on microwave circuits that were built
on printed circuit boards. It was replaced by the simpler to make micro-strip
line, which is a strip of metal(copper) on one side of a board that has a ground
plane on the other.
