The Fine Things are Always Hand Made
The Berkshire uses an RCA LC-1 speaker with the independent tweeter residing inside the woofer voice coil area.

Very nice! now I know which speaker is missing from my unit. Do you have a any suggestions for an acceptable modern replacement?
Ken, the speaker impedence is supposedly 16 ohms. The cast frame is made so the speaker face mounts flush with in the enclosure. You might be able to see that on my other pictures. You should be able to mount any good 15" PM wide range 16 ohm speaker. I got the chassis' and speaker from the original owner in the late 70's. It was all mounted in the Regency model with projection TV. At the time it was so large I had no place to put it in our house so I took the what you see. Right now, I don't know if there is a market for the Regency, it's so large. I built a cabinet to house the chassis' and speaker. I restored the electronics a couple of years ago and it works very well.
Also, when I acquired the set, it was missing the record changer(s) and three of the four knobs on the tuner chassis were missing. I made a mold from the existing knob and reproduced the other three. The home where I got the Berkshire equipment is a story in itself. The older, ailing gentleman had a large record store in Philadelphia in the 40's and 50's but had a disagreement with a partner. He moved the entire record stock to his home and there it sat for decades. He became ill with diabetes and became a recluse and sold records (78's & LP's) from his home. There was a post-war Capehart there as well. It had been picked over, unfortunately.
The original speaker is the RCA LC-1. The tweeter is mounted in the center of the woofer voice coil area. The speaker crossover "network" is a single capacitor. The LC-1's show up on Ebay from time to time, but the prices are rediculously high.
RCA literature identifies the RCA Model 515S1 speaker as a direct replacement for the original LC-1. The 515S1 speaker does not have a cast basket but it is much more affordable.
Tom and Norman ... Thanks to you both. This 'new' radio has me energized again. There are too many projects around here but this one will go on the short list.
A replacement speaker is fine with me. Now if my friend finds the power supply I will be in business!
Ken, you spoke of needing a power supply? The two chassis' plus a speaker are a complete 'receiver'. I didn't see the heavy interconnecting cable that connects the tuner to the amplifier/power supply chassis in you pictures. -Tom
Argh, the connecting cable will be a bear and finding the connectors as well.
