Seriously now, since Philthy has already insulted everyone
here (and elsewhere for that matter) that are likely to be
of any assistance it is amazing that he expects them to help
him now! Geeeeezzzz! His hide must be thicker than his skull ;-)

I would offer to help if I had ever seen the inside of a 405.
I enjoy Phil's antipodean charm, even when pointed in my direction.
I guess Trevor Wilson would advise that the LM301 is nothing but
a distortion generator and should be replaced by a 5532, and to increase
the psu caps to 0.5F. Jute would recommend reducing the capacitance to stop
the sound becoming sluggish. I don't believe that anything wonderful happens
when Z1Z3=Z2Z4 because at audio frequencies you are multiplying zero by
infinity to get any number you want.

Plenty of advice, circuit diagrams and capacitor kits at http://www.quad405.com
