[78-L] BE Nit Pick

[Michael Biel]

Not only is this a worthless reference source, you read it wrong.  The
1911 reference is to an "electrodynamic telephone" which is not even
discussed by the company.  It probably was an experiment by one of the
two founders, Edwin Pridham and Peter Jensen.  Together they worked on a
loudspeaker in 1915 which is what the next reference is to, but this was
just when they started experimental work.  They formed the company in
1917 and did not have any big success until 1919 when they developed a
public address system that was used for an outdoor speech by President
Wilson.  Here's a picture of it from that year  
http://www.powerhousemuseum.com/collection/database/?irn=322920

Have you looked thru radio journals from 1920, 21 and 22 to see what
kind of equipment was actually available on the market?  THAT is where
you get information. You don't go to a web page from a guy selling a
stock certificate to paper collectors. He doesn't know anything about
radios, only about paper collectibles.  When was the last time you
wandered into an antique store and got accurate info about phonographs
and records?

Furthermore, notice the item "1922 first amplified phonograph".  I know
what that is about because it is based on the "Magnavox transmitter
tonearm" they advertised in 1922 which has a carbon mic stuck halfway up
an acoustical tone arm.  On the company's web site they list this for
1915 and say "now the whole family can enjoy the music".  How can we
trust a site that doesn't even understand that there were horn
phonographs in 1889 a whole auditorium could enjoy.  Plus, Paul Fortin
at GE had developed an electric pickup head in 1915, while the maganavox
arm in 1922 used an acoustical reproducer.  All this stuff is not being
written by researchers or experts.

FIND ME AN AD FROM 1920 THAT SHOWS A RADIO RECEIVER WITH A LOUDSPEAKER. 
It's got to be an ad printed in 1920.

Since Magnavox was founded in 1917 it would be interesting to have the
URLs of the pages. I see a lot of stuff on the web that isn't worth the
paper it isn't printed on. Since most radios were crystal in 1920, and
the 01 tube was not really strong enough to drive a loudspeaker,
headphones were usually the onlt things that were in use -- even in the
radios Westinghouse was selling at the point of KDKA. A year or two
later someone was marketing a horn you could clamp your headphones to in
order to get a little volume.

An eb page is just like a web page except with a silent and quite
invisible
W. The 1911 date was from a page about some Magnavox paperwork I
believe.
I could Google it again if you'd like.

What's an "eb page"? Who wrote it? What is the reliability.

Magnavox had developed a P.A. system in 1919 but it was something that
was very rarely used and required a roomful of batteries and tubes.

the ballroom crowd gathered around a radio with a horned loudspeaker on
its
top to listen to the Harding-Cox elections, supposedly coming from KDKA.
 
I don't think people were listening in 1920 to a speakered radio;
earphones
were the method of hearing that early time, right?!
