There is still a fair bit of AM activity on the 40m, 80m and 160m bands. I imagine there would be a handful of hams in your area that would be interested in playing with that kind of gear.
It could have a vibrator style power supply in it which would allow it to be run from either 12 or 24 volts DC. Typical of the era the manufacturer would have recommended an end fed type antenna and there would have been a table in the back of the manual explaining to non technical type how the antenna should be built. There would also be notes explaining how to adapt the tank coil and perhaps additional filtering. Replacing the crystals with a AD9850 type VFO/Oscillator would be a simple way to get this gear onto the ham bands.
The resale value would not be very high. I think you'd be doing really well indeed if you could extract $100 out of someone for the set.
Thanks for the info....
I would dearly love to get hold of an original/copy user manual for it.
I am actually more curious about it as I know it is old and therefore to me something of interest/curiosity and worth holding onto as a keepsake.
I wasnt trying to get it appraised or anything.... just wanted to know what it is that I have.
In-fact I only paid $50 for it and it seems to work.... just having it sitting on my bench really gives a feel of antiquity and contrast amongst my other radios.... kind of a now and then feel..... humble beginnings lol
I was toying with the idea of giving it a fresh coat of paint matching the original color etc.... but decided that would only detract from the historical significance.
