It would be advantageous to run the circuit off a Mains supply. Those Inverter-based circuits are really sensitive to battery voltage. Quite understandable, as the non-linear point sets in at a certain level below V+ (positive amplitude) and above 0V (negative amplitude). I built such a circuit with adjustable voltage - and there was only one usable setting for the supply voltage, AFAIK. A volt below this - and the thing sounded like ****.

I also seem to remember that those circuits should be built using an even number of inverters in the signal path, as distortion is not symmetrical. After 2, 4 or 6 inverting stages it's evened out.
