My current mirror variation on the Baxandall Class-D oscillator - minor revisons...

[Bill Sloman]

I\'ve changed the circuit a bit - essentially taking out bits that didn\'t add value - but I did change the Sallens and Keys filter to one with a bit of gain that gives you a maximally flat time delay with standard value components.

The performance is marginally better.
