Hi folks, people, demons and anyone else hangin around.
I have posted up another page for as 1/2 decent wien bridge oscilator which has 6 F ranges to give 1Hz to 1MHz. Instead of using potentiometers or tuning caps it has a two ganged wafer switches each with 12 pos x 1 pole to give relative F = 1, 1.2, 1.5, 2.0, 2.5, 3.2 3.9, 4.7, 5.6, 6.8, 8.2 and 10..0. These F appear at fairly evenly positioned points around a dial covering 360 degrees with 12 F marks.
A fairly decent Schmitt trigger square wave maker is included.

Address brick bats carefully, so I may return them with gusto and a better aim than yours !
