[The Aeolian]
Radio Process Co. "The Aeolian," ca. 1946

Tube complement: 6SA7 mixer/oscillator, 6SK7 IF, 6SQ7 detector, 6K6GT audio output, 6X5GT rectifier.

Approx. 10-3/8 inches / 26 cm wide.

Since I found no information about this radio or this company in my references, I had to guess its year of manufacture.  The radio provided the following clues to help me:
  • It uses tubes that are common in radios made in just a few pre- and post-WWII years.
  • The radio uses an electrodynamic (has field coil) speaker instead of a permanent-magnet one.  Electrodynamic speakers were almost completely abandoned by 1946.  I'm aware of only a couple of other postwar designs that used 'em.
  • The radio uses a built-in loop antenna.  Loop antennas became common by 1940 or so; they were almost universally used after WWII.
  • The type of plastic insulation on the loop antenna wire, and the appearance of the underchassis resistors, are postwar.
  • The overall construction quality is rather cheap, and evidences little attention to detail—this is a general characteristic of postwar, not prewar, radios.
Based on all of the above, my intuition says 1946.

Some of the original paper condensers (which I replaced—they were leaky) were labeled "Tuffies, McMullen Products, Santa Monica."  Radio from LA, condensers from Santa Monica—I was humming Beach Boys tunes and dreaming of wide palm-tree-lined boulevards while working on it.

Another interesting thing about this radio is that it's an AC-only (transformer powered) set, not the AC-DC (transformerless) type that one would expect in a small Bakelite table radio.  My Packard Bell 5FP is also AC-only, and it's also a California radio.  Perhaps Los Angeles or other California cities prohibited the relatively hazardous AC-DC sets.

Oh, and yet another thing about this radio:  When I received it, it had the wrong knobs.  (I know this because they were marked with wrong functions, such as tone or radio/phono.  Besides, they looked wrong in terms of style and color.)  Since I have no reference information about this radio to help me determine what the original knobs look like, I just selected some knobs from my "junkbox" that I thought looked good on this radio.
