I like how the radio chassis has its own power transformer. It's neat how it's a series string chassis with a 35W4 rectifier. I could actually remove it and use it as a stand alone tuner if I wanted to.

The tweeter output is very low, likely needs a new capacitor. The whole set works well actually, aside from this, but I will change the caps all the same. Too bad Sams didn't do Canadian products, it may make the service info harder to find.

Bass seems exaggerated, I it booms like an old jukebox. It actually adds a plesant quality to the sound which i quite like.

There should be some coverage in Beitmans, 1956 or 1957 manuals. The amplifiers seemed to be the same. I liked the way RCA used 6CG7's instead of 12AU7's.
BTW, RCA used that tuner as an option, that could be added later, in their Hi-Fi and stereo consoles.
The chassis was similar to their AM-FM table radio, of the day. The transformer is an isolation transformer with a 6 volt winding for the dial lights.
It also uses a 19X8 tube as an osc/mixer, which isn't that common of a tube.
