Zenith Model 5-S-320 Table Radio (1939)
Copyright TubeRadioLand.com
The Zenith 5-S-320 (5S320) table radio
was introduced at the same time as its
smaller kin, the
5S319.  For what was
considered an upgraded cabinet, it cost
$5 more.

Both the 319 and 320 use the same
5529 chassis type. The schematic may

Neatly designed for the table top.
