Interesting to hear about the output transformer problems.
I have a Quad II which I 'rescued' from a company that went under. The Quad is actually new, & appears not to have been used, & still in its original but tatty box.
I've had it for around 40 years, & checked it out a few months ago. Unbelievably, the output transformer is o/c on one of the secondary windings!
I'm wondering if perhaps the wire was never soldered to its relevant tag.
But how did it pass a final test?

I'm hoping to sneak the transformer past my wife into a warm oven at some point so that I can disassemble it.

Incidentally Canford Audio used to do an HQ 100v line 'Music' transformer, which I have installed where I needed better quality speakers, & the results were very good.

David.
