"Eiron"

I would offer to help if I had ever seen the inside of a 405.


** Dear friend - a treat awaits you.


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.


** The justifiably famous Quad 405 needs no snake-oil mods whatever.

Early examples simply need their small electros replacing - as it seems
Quad were royally dudded by the Dumbkoph Krauts at Roederstein who supplied
allegedly "sealed, long life caps" that were anything but !!



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.


** Completely off with the fairies stuff.


Plenty of advice, circuit diagrams and capacitor kits at

** All of it snake oil inspired ********.
