Just Wondering ??

Hi All;
I am pretty sure it was not a car radio, turned home radio.. I would say it was about a 5 to 6 tube radio.. I don't remember if it had a transformer or not.. I just remember it was inductor tuned instead of Capacitor tuned, since I had never seen one like it before.. I was going thru Radio repair class and I wanted to know what I had, sitting next to me in my bedroom.. So, I took off the back and looked at the inside..
THANK YOU Marty

As a long shot, look up the Detrola website.
It shows pictures of the many models, that they produced.

Hi All;
I found a picture of a model of a Detrola 571, that is close.. I will try and post a picture of it.. below.. What I had was all Bakelite, brown in color with white speaker grill (Maybe) and had inductor tuning.. But the picture is close enough..

THANK YOU Marty

One nice feature of this radio is that the frequencies are nicely evenly spread out across the dial, not with the high frequencies scrunched together on radios using a tuning cap.

The wire on the coilforms of the variable inductors are wound with varied spacing between turns, so that linear movement of the ferrite core will produce a linear change of frequency.

It was worse with the Japanese radios.
There wasn't too many radios that had the dial scale reversed.
Maybe they were planning to use a wavelength scale, instead of the frequency scale.
