Nice.  I used to work on such stuff in my Dad's radio & TV shop.

I love to cook with wine.     Sometimes I even put it in the food.

Shortly after my discharge from the Army in 1945, I built one of these:

For the schematic: (It really did use thirty tubes!)

The pre-punched chassis was available on "radio row" in NYC, as were a
set of the IF transformers, the RF tuner and the flyback transformer.

For the rest, I scrounged from various places, with the exception of the
thirty tubes, which I had to buy.  It wasn't quite like a Heath-Kit,
since the only instructions was the schematic!

We had that set until 1955.  After altering the AGC to avoid "flutter"
every time a plane flew near, it was a pretty good set!

Nice. A friend's dad had a TV with Channel 1 -- he started out after
the war as a TV repairman. He also still had a tool box, a tube box,
and some Sams Photofacts from the late 40s/early 50s.


You scrounged the flyback and the coils, too?


We kept our Hallicrafters for ten years, too.
