This knob is the medium control knob found on the Drake 7 line equipment such as the TR-7 transceiver and the R-7 receiver. On this equipment, there are a couple of places where these knobs are utilized. Please do not confuse this knob with the small control knob which resides on a stacked pot arrangement. These knobs are very hard to locate in good condition and this one may show some minor signs of use and wear, but certainly nothing really bad. We show a couple of samples of knob condition in our pictures at the top of this listing. We have graded these knobs into 3 categories according to condition and this is the medium #2 grade which may have marks on the bezel and is neither perfect nor subpar. These knobs can become lost or broken, and while finding a replacement may not be terribly challenging, finding one that has respectable appearance can be difficult.
