The 5-R-135 was an entry-level radio in Zenith's 1937
line-up. It was introduced in late 1936 with a selling
price of $29.95. Even though the tapered tombstone
style cabinet is somewhat plain in appearance, it sold
well and is a relatively common find today.

For 1936 & 1937, Zenith designed their sets to
use either metal or "metaglass" tubes. This was
prominently reflected in their advertising and was
noted on their schematics by the showing of both
designations (e.g. 6A8 for the metal version and
6A8G for the glass type).
