Hi,
I designed and build a very simple Wien bridge audio signal generator in the frequency range of 0-10Khz.
It has 2 scales 0-1khz and 1-10khz, and use a Jfet transistor for the negative feedback.
It is powered up from a single 9V baterry and uses a dc-dc converter(LM555) for the minus rail of the LF356.
The generator it's very stable and the output it's variable from 0 to 5V.
The schematic and picture can be found on my site : **broken link removed**
