Alan’s Automatic Audio Leveling Circuit (Limiter)

I don’t get quite the same results – expected! – as Alan as I’m using different diodes pairs with 0.2V bias and 0.3V bias, but overall get a limited signal out from about 100mV – 500mV limited. Need to tweak some components for this..I’ll prob come back to this if I get all germanium 0.2V bias diodes..:
