Tektronix TAS 220 Oscilloscope Knobs

Have a Tektronix TAS 220? Have those long knobs for "Variable" and "Sweep Variable" broken for you, too? Good news: now you can just print a new one, and your semi-vintage oscilloscope can live on for a few more years!

There are two knobs attached:

* A longer knob designed to replace any channel's "Variable" knob named "*variable*" in the attached files.
* A shorter knob designed to replace the "Sweep Variable" knob named "*variable sweep*" in the attached files.
