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

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

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?
