Hello All:

Yes this had to run in someone's mobile, I would think it took way over
200 amps to run. This really has to be one for the hall of fame!

It would take nearly 20 amps just to
keep it on standby.


Closer to 10 amps.


.....A DC pig it
definitely is. However, as far as
output, by todays standards, it isn't
that big a deal. A daily-use 8-pill
is easily its equal.

I saved the photos on a disk. Where would you put this monster in a car
or truck?!??!!??!?! Hehehehhehehehe

On the floor, in the trunk, or in A
custom box in the bed. In those days
the radios didn't have the frequency
coverage that is common today. That
means that once it was tuned it could
be left alone.


What a load of hogwash. This amp has a tuned pi-tank output that you
can clearly see in the pics; i.e, you need to retune if you change
freqs. Tube amps can be designed to be broadband just like solid-state
amps, and solid-state amps can be built with tuned output tanks. But a
broadband amp -- tube -or- transistor -- eliminates the tuned output
tank, the result being harmonics that increase with non-linearity. The
only difference between 'then' and 'now' is that ampheads these days
don't give a rat's ass about harmonics bleeding all over the spectrum.

And as far as frequency coverage is concerned, the range of bipolars
is generally narrower than power RF tubes, the latter being usable
from 0 Hz all the way through to their maximum frequency. In fact,
most are rated in their data sheets for use as audio amps. Even
smaller RF tubes like the 6146 have been used in guitar amps. You
can't do -that- with a 2SC2290.


And WHAT mobile antenna would hold a full KW, other than a 102 inch
stainless steel whip ?

A Firestick (heliwhip), the Francis
whips, or even a K-40 or an Avanti
Mobile Moonraker that was tuned right.
It has to be realized that when all was
well that unit was good for 600 dead-key
and 1200 peak.


More like 300 dead-key (RMS/AM) and 1200 PEP (SSB). And to think that
after all these years you -still- haven't learned the difference. Go
crawl back under your rock, Bill.
