SINGLE_POT_WlEN

Can be tuned from 340 to 3400 Hz with single 150K Iogarithmic pot. Output is constant over tuning range. Opamp can also be 741. Components in the two arms of the Wien bridge have Iarge ratio to each other, so attenuation of network is only slightly affected by changein one of resistors.-P. C. Healy,Wien Oscillator with Single Component Frequency Control, Witeless World, Aug. 1974. p 272.
