-
Color: Ivory. There are different output tubes listed: Beitman featured the 50L6GT, Rider's a 35L6GT, while Sam's shows a 50L6GT in the schematic, but mentions also a 35L6. To be on the safe side we list the models separately, since printed labels stating different tubes had been applied to the radios.
