This radio, acquired at a garage sale, employs following tubes: 6A7,
6B7, 42 and 80.
The back panel contains the text
"Magnetic LOM A" and "License SBR-SEM-BELL"
and the chassis shows the number 40868.
Magnetic is a SBR licensee and the chassis of this radio appears to be identical to SBR model 373A
(which is also in my collection).
