"Patrick Turner"
A short note to all:-
I was not completely happy with my old page on re-forming Quad-II amps for
improved performance.
** Nor was anyone else .
So I have now re-edited all schematics and removed much BS and added more
possibly useful stuff over the last month.

** The notion that the dual EF86 stage has less THD than the output stage
need correcting.
It does not, it has far more - about 5 times in fact - do our own test,
with the EF86s removed .
The correct result is in the vicinity of 0.2% THD at 10 watts and 1kHz
rising to 0.6% at 15 watts.
I consider myself well pre-battered by Quad-II zealotistas
** The Turneroid is like that mythical duck that all water runs off.
For "water" read rational thinking and fair criticism.
Quack, quack.....
