Wrong.  Allied Radio was one of Radio Shack's competitors.  Radio
Shack had several competitors, all of whom were (in my opinion) better
than Radio Shack.  There was quite some choice in those days.  Alas
the business became non-profitable, probably because of the integrated
circuit.  Radio Shack bet on computers (with its TRS80 series) and
survived.  The others (or most of them are no more).

Thanks Pat, I'm proud of you!  'Had me worried for a second!

Allied Radio!  I remember the thrill of getting my mother to take me
into Chicago to pick up the speakers for my "Sweet Sixteen" speaker
encloser which I built from the plans in "Popular Electronics"!  Those
were the days.

[Moderator's Note: Then you no doubt remember the big warehouse store
they operated at Western Ave. and Washington Blvd., right across the
street from Olson Electronics (remember them also?).  In the late
fifties and early sixties we'd go shopping there on Sunday. Unless you
went in right at 10 AM when they opened you could count on being there
several hours before you got out, what with the sales people having to
call to the back for 'stock checks' and such. Credit approval could
take another thirty minutes (they did their own credit in house) and
you would then wait until your name was called on the public address
speaker: "Townson, go to cashier seven". You'd wait in line there for
maybe ten minutes to sign off on everything and pick up your package.
After Tandy/Allied closed the store, it was vacant for a few months;
since that time it has been a local office for Illinois Public Aid.
Olson Electronics remained open several more years but I guess they
are gone now also.  That whole neighborhood is the pits now:
stereotypical inner city advanced urban decay. Nothing around there
now but the welfare office, a couple of liquor stores and the
omnipresent Illinois State Lottery agents.  *Ancient* painting on the
side of the welfare office now mostly faded away welcomes everyone to

Hi Patrick,

I see from your postscript to my letter that you shared some
electrifying experiences with me ... I got zapped by plate voltage a
few times while hamming, thank God not on a linear amp.  The best zap
I ever got was off a power supply I made for a linear accelerator in
high school.  This was basically a Tesla coil, but the primary was
tuned and drew about .15 amps at 12,000 volts.  I was playing with it
one day using a four foot florescent tube attached to the proverbial
ten foot pole.  A lightning bolt traveled down the tube, down the
pole, down the *outside* of my arm and under all my clothes where it
went to ground through the safety kicker switch I was standing on.

The only place I got shocked was where the bolt went through my toe.
It left a little black pinhole in my big toenail.  Oh, and when this
happened I got thrown off the kicker switch, which shut down the coil
just before I hit it.  I got a second shock from the large static
electric field that the secondary coil always built up after a minute
or so of operation.

This tall but true tail has nothing to do with Telecom, I present it
here for your amusement.  The coil was designed, BTW, to put out 2.5
MEV of tuned power to a linear accelerator tube, unrectified.  The
tube was short enough that AC merely made it put out a beam from each
end.  Vacuum problems put the fini to this project, as well as
radiation concerns from the people granting me money to build it.  I`d
guess that of the 2.5 MEV I was shooting for, 1.5 of it vanished in
solid blue corona.  The device built up enough ozone in the room it
was being tested in to give one a severe headache in only a minute or
two of operation, and lit florescent bulbs in several houses nearby.
TVI and RFI were problematic as well.

(Ob telecom: Holding on to both wires of a phone line when it rings is
even better than casual contact. Learned that when I was only 16 ;-)

Ah, memories of sweet youth, Pat!  When I was just a little electron
herder, I used to drool over the Allied and Olson catalogs for hours.
(after all, Nome, Alaska had very few electronics stores in those
days) The other two standbys were Newark and Lafayette. I haven't seen
anything indicating that Lafayette is still around, but Newark is a
regular supplier to my place of employment.

I was also a Heathkit fan ... built a HW-16 and a digital clock, among
everything else. The clock still runs, and will be 20 years old next
year. If Heath is still around, I think I'll send 'em a picture of it.

It's illegal to *sell* ten meter linear amplifiers commercially, but
legal for hams to alter linear amps for ten meters for their own use.
You can also sell them non-commercially (e.g. at hamfest flea markets
or the local swap-and-shop net).
