[GreenKeys] period HF receivers

[Leanne]

My first SX-28A came from a chaplain's kit.It was mounted in a lectern along 
with a record player and a large speaker.
I acquired a second one and used then in diversity reception through a big 
Military dual  IF converter. I found another
non-functioning receiver for parts. Ah, the good old days listening the 
"music," from the model 19 typing away.

The Hallicrafters SX-28 (late 1930s) and SX-28A (1940s) had a jack in the
back of the receiver for a phono input, and the audio output stage was
push-pull 6V6s to drive some serious loudspeaker.

I don't know about the keyboards.  Probably was the same as typewriters of
the day, which were mainly operated by female secretaries.  However
Teletype was used by railroads (mostly male until WW-II) and military
(male in the field, females stateside in office work)  And I would imagine
machines in TWX service were mostly female operated, just like
typewriters.  And Western Union had operators of both genders.

I think that was more a matter of office equipment styling in general,
rather than to appeal to the operators.  In the 1930s there was Teletype
equipment with wooden tables finished like furniture, and Model 15
cabinets with hand-painted simulated wood grain finish.  That would go
in offices where the desks and file cabinets were wooden, and would fit
right in with the decor.  After WW-II steel office furniture was the
norm.  You might compare IBM equipment as well.  1930s the machines had
cast iron legs that would remind you of a wood stove in a country kitchen.
1940s-50s they had sleek equipment with rounded corners.  And after that
sharp corners and chromed legs were in vogue.  Companies had to keep
changing styles to make the new equipment look more modern than the old.

I believe so.  I don't think the telephone company would send out a
repair man just to change the ribbon in your TWX machine.  Wire services
furnished ribbons to their subscribers but expected the subscribers to
do the changing.  And that was before you could get cheap plastic gloves
by the gross to keep your hands clean.
