I have a Stewart Warner radio with following tubes:
5U4,6D6,6A8,6SQ7,6V6, and tuning-eye tube. The only
markings on inside of cabinet is R-1721A. I have not
been able to locate a schematic because uncertainy
of Model No. Any Help would be appreciated.
Thanks,A.B.Tiller

: The previous tube listing was in error. There was

not a 6D6 tube as listed, but instead used the tubes

as listed: 6K7,6A8,6SQ7,6V6,5U4, and 6U5 tuning eye.

The cabinet is wooden, it has a BC,Police,and Foreign

band. The tag inside the cabinet appears to read

R-1721A (stewart-warner).It was possibly made prior to

or just after WWII. Any help identifying or steering me

to a schematic would be greatly appreciated. Thanks
