I would keep the Stromberg and try getting it to play better, it's a far better radio then a Radiola 60 Brunswick clone would be, if only for the few years extra technological refinement. In answer to your question yes Brunswick made lots of sets without a phonograph, they made table model versions as well with a seperate speaker. RCA did not make these sets, Brunswick made these under license, RCA didn't make anything until they took over Victor. The power supply chassis does just that I believe, in my Westinghouse 89, which is similar to a Radiola 63, the only tube in that chassis is the type 80, the power output amp is on one end of the tuner chassis.
