I have assembled this entire circuit except this one part. I have never seen this symbol before and I know its not a diode. So what is it?**broken link removed**
The R1 component is a potentiometer, but how does that sysmbol incorporate into the design? I have everything wired up except that and Im not sure how to proceed.
My guess is that it bears a strongly resembles the attached drawing taken from an old Forrest M. Mimms III circuits notebook Circa 1982. The part is a potentiometer and yes, the circuit originally posted is poorly drawn. The attached works fine. Sorry the original paper is yellowed.
