Hi Greg are you talking power transformer or Output on the quad II. Power wise is relatively eay as it's HT about 620V Centre tapped (310-0-310), then 5V for the GZ32 and 6.3V for heaters.
OT is a little more tricky as it has a centre tapped winding for the O/P Bottles cathodes. Very unusual design and part of what makes a quad sound like a quad.
I was at Syntec from early 91 until end of 95 with Murph in the heydey of A820s, SSL 4000 G series and Dolby SR.
Sadly Murph "moved on" in July 2008. I have a lot of his old Manuals and components collected over 60 years (Including 8 x KT66 GEC Tubes, still in original Boxes) that his family gave me after his will was sorted and no-one wanted them. I also have one of Murphs old Quad 303 Transistor amps. Murph taught me to "love the tape recorder".
A fabulous teacher , there are many who miss him.
But when the Quad goes on and a tape plays on the old Revox D36 Valve tape deck, I think of Murph with a wry smile and enjoy the sound of an all valve repro chain....very warm.
