    Hello,

    Can you post a schematic of the intended circuit?

    Is there a special reason why you want to use transistors ? If not, you might consider to use a good audio op amp instead - you can achieve lower distortion. The attached file by #12 shows some examples.

    Also AN 43 "Bridge Circuits" by Jim Williams, discussion of Wien bridge oscillators starts on p.29:
