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. MIchael VE2BVW |

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. 73, Ed Knobloch |

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.
