That is it. I was only 14 when this issue came out. It also had the 420mcs super-regen transceivers in it that was used in a line of sight DX of 30 miles. I remember that one too.
I think over a few years I confused this amplifier with the SBE amplifier that came out a little later.

I have been looking for an article about a suitcase kW amplifier using a
load of sweep tubes. directly off power line power supply (voltage
multiplier) and a broadband matching network. Not interested in building one
because there are all sorts of problems with the idea. I think it was in
late 60's but I can't find it. Perhaps it was not QST.
Anyone remember it?

Yes I remember it, although I don't remember much about it other than
thinking it was a poor idea at the time.
It may have been in 73 magazine around 67 or 68?

Hi Bill,
i do remember seeing an article with 8 to 10 TV horizontal amplifier sweep
tubes. They were Philips or Valvo, or Siemens, marked as PL519, PL509 and
not sure PL505. There were also line of EL519 but, faintly they did not fit
the drawing due to heating.
The PL519 were either designed for 24 Volts or similar voltage, thus they
used quite some number of them.
It was published in our Radioamater , same as QST as national amateur radio
magazine. And when our "brother ina arms " CBers find that, you have got
number of amps...
Also, if my memory serves me, there was an article in German CQ-DL thus,
play bit with google ans see, if you got any respones...
Kind regards Bill,
Nermin S58DX

Hi Bill again :)
well, it was faster then i thought.
Anyhow, check QEX June/July issue
for 2KW-linear maplifier by Saulo Py2KO.
Unfortunately my membership at ARRL does not allow me, to download the
article and will see, if scribd will let me do it for free as well.
Also, there is an article on web by PA0FRI with 4 pieces of PL519...
kind regards,
Nermin S58DX
