This is an exact reproduction knob used to replace the old gnarly or missing tuning knob on the models listed below. It is a solid knob and won't warp like the hollow, thin-walled original knob.

Used on Zenith models: 6J436, 6J463, 7J323, 7J328, 7S363, 7S364, 7S366, 7S367, 7S368, 7S369, 7S370, 7S371, 7S372, 7S373, 8S359, 8S440, 8S443, 8S451, 8S463, 10S452, 10S464, 10S470, 10S491, 12S371, 12S470, 12S471, 12S474, 12S475, 12S479, 12S491, 12s492, 12S494, 15S372, 15S469

Attached with 2 set screws (included).

Dimensions: 1-1/2" diameter, 11/16" tall, 1/4" hole

Used in conjunction with a smaller on/off/volume knob (k134) listed on eBay. See my other listings.
