I did a little exploratory surgery tonight. Here's what I found.
First, I had to disconnect the speaker. It had been spliced in and wrapped with old cloth electrical tape.
One of the five speaker wires is not connected. Maybe it's a center tap ?
Here's the chassis. The tuning cap turns freely, but someone pencilled in some call letters on the dial
Here's the underside. It appears to be more original than I had expected.
There's a coupling transformer inside each of those copper boxes.
One section of this bulging Ariston Lab. cap isn't connected. I suspect it was a replacement for the big old can capacitor.
Cool Aerovox cap label.
I wonder if these Sprague "midget" caps are original ? I don't think the wax caps are.
Here's the speaker. The surround is just an extension of the cone. I wonder it it's been reconed ?
The cone moves well with no scraping.
