1933 RCA & General Electric Reproduction Radio Knob – Plastic Set Screw Style

The Knob That Belongs on Your 1933 RCA or GE Radio

Finding the right reproduction knob for a 1933 RCA or General Electric cathedral or tombstone radio isn't easy — most reproductions are either the wrong profile, the wrong finish, or the wrong fit. This knob is molded in plastic to faithfully simulate the appearance of the original wood-grain knobs used on these sets, and secured with a set screw for a firm, rattle-free fit on a 1/4" shaft. If you're restoring one of the most iconic American radios ever built, this is the knob that completes the front panel.
