What's the oldest thing you've worked on?
 

Electricity has been around for quite a while now. I'm not fond of working
on vacuum tube stuff because it's (to me, anyway) an ancient technology. Of
course, other techs are thoroughly familiar with it and have no problem
restoring tube radios built in the 1940's.

The oldest thing I've ever tried to fix is an A****er-Kent radio receiver.
I don't know when it was built but it had some ANCIENT vacuum tubes, all of
which had the heater filaments open. I didn't even try to replace them or
go any farther with it. I'd say it could have been made in the 1920's.

But there are lots of older items out there, some of which may still be in
constant use, such as motors in industrial applications that are
non-critical (such as ventilation fans).

What's the oldest electrical/electronic item you've worked on?

Just curious.

I've worked on some of the early 50's TV sets, and radios from the mid 30's
and up.

Today's TV's and radios are all very sophisticated software driven devices
with computer devices behind them.

The realizes of the changes that occurred are incredible when you understand
what is going on.

Unless you count rewiring 1920's light fixtures, probably 30's radios are
the oldest thing I've messed with.

Crosley radio from the early 20s. Two wd 11 rca tubes in a super
regenerative circuit. It used 3 batteries for filament, grid bias and
plate. The filaments were also the cathodes. It worked very well
with headphones. Chuck

1928 Freshman Masterpiece TRF Radio which uses a 50 output tube for the audio,
have you priced used #50 tubes lately, around $150-$200 each!

A friend of mine once came across an old tube radio. Not having an interest
in it, he passed it on to me.
I cannot remember the exact model, "R" followed by a number... I got rid
when it was working as I didn't have the space for such a large beast.

I happen to have some old diagrams... radios from the 1940s/1950s, a couple
of TVs from the 1960s/1970s and some TVs from the 1980s. I also have some
old tube and valve data.
If it is worth the time (people want to see them), I could put some of it on
one of my Web sites. At the moment I am putting together some old
information for someone... anyone remember the Sinclair ZX81 computers?
Those were the days, a whole Kilobyte of RAM and several minutes to load a
program from the tape :-)

Pretty good trick. I don't believe vacuum tubes existed in 1899.
