This BRAND NEW RL Drake MN-2700 Main Tuning Knob , is the original Fluted Daka-Ware Tuning Knob, with a 2 inch Diameter Skirt and a brushed Aluminum Inlay. It will fit on a 1/4 inch shaft.This Knob is used on the Drake MN-2700 Tuner as well as the L-7 Amplifier.I offer two types of this model knob. One has a white pointer line on both the knob and the skirt, and one does not have a white pointer and is normally used when a pointer line is not required as when used with a reduction drive vernier dial. The Drake MN-2700 Antenna Tuner uses this knob with No white pointer line.This listing is for the knob with No pointer line.This knob is made from general purpose Phenolic, with a gloss finish, which is very durable. (not like molded plastic where one touch with the solder iron and it melts immediately!) If you have this type of knob on your gear and it is marked up, chipped and scratched, this knob will make it look great again! These large knobs are used on MANY Amplifiers, Antenna Tuners, and other Amateur Radio Gear including the following brands: Ameritron, Amp Supply, Amp International, Clegg, Dentron, Drake, Hallicrafters, and Swan This is only a partial list and this Large Knob was used with Hundreds of radios and electronic gear.If you have a piece of gear with this type knob and only need a replacement inlay, I have them available in another listing.
