Since when have CB amplifiers been recognised as boatanchors or is this

Running more than 4 watts on 27 MHz in the US has been illegal since
CB became legal here - 1961 IIRC. I don't know what the rules are in
Oz.

Al, yes more or less the same rules in Oz - type approval etc, but this
gear is not considered as a collectable boatanchor though, so a bit off
topic in the boatanchors forum - maybe an excess of cross-posting.

My fault for not noticing your ng. I guess *newer* amps wouldn't be
too collectable, although I do recall an article in QST (or was it CQ)
many years back about a pair of 4CW300s running in the trunk (boot) of
a car. That kind of amp would probably be considered pretty
collectable.

There was a guy, well known but I can't remember the name, something like
"Jo Emmings", who wrote a number of articles about fairly unusual amplifiers.
He either worked for Eimac or Varian, or a company that made vaccuum
variables. The articles I've seen were in CQ, in the late fifties.

That author was Jo Jennings, W6EI. He owned Jennings Radio,
and manufactured vacuum variable capacitors and vacuum relays,
which were featured in his designs.

The CQ "New Sideband Handbook" (1958), edited by Don Stoner,
has a 4CX1000A linear design by Jennings. He got the rf deck
(less blower) to fit in a box 6" X 11" X 7".
The design used a passive grid circuit, and could be driven
by a CB power level rig.

Who had the Caddy with the Collins S-Line complete with 30-S1 mobile?

No, as someone pointed out, it was Jo Jennings.

I do recall an article in "73", I think in that giant November 1972 issue,
about someone running a kilowatt from a fancy car. But I remember it
as being a KWM-1 (though maybe he was showing an earlier version) and
a Heathkit amplifier.

Memory also says that article was by Don Miller, the SSTV guy not
the DXpeditioner.
