Everyone should get the Quad expert here, Phil Allison, to
tell you how *HE* went about buying second hand Quad 63s.
Yes he tried very hard to get sequential frame numbers only
to find out later how there was 6dB difference in SPLs. He
then had to sue the second hand dealer and it took him
nearly 12 months to get his money back.

So "Caveat Emptor" and "try before you buy". Two very good
bits of advice.

Cheers TT

Well FWIW I was over at the Quad factory some years ago and saw a demo
of taking any stat off the production line and comparing it with an
early sample and the resultant display of a square wave replayed 'thro
it and the phase cancellation when the wave was switched out of phase.

Very impressive

Not the ESL63 !!!

ESL 57s were never so consistent .

Your story is fake.

Sorry Mr Allison sir;( most 'umble apologies meant the 63!, how should I
do me penance ?, grill cloth and ashes fer a week will that be OK?, or
do you need some further appeasement?.

Well, apart from those before and after the power supply mods, Walker said
they were. And I've had wildly varying serial numbers sent back for
overhaul and had them come back sounding the same. And *he* told me
matching pairs referred to the woodwork.

YMMV.

Even if you did - it does not constitute information about ESL 57s.

No - it was an off the record conversation after an IBS meeting he'd been
invited to.

It's good enough for me.

Considering each and every one was quality checked after repair I don't
find it unsupported? Have you ever visited the Quad factory and had
speakers repaired while you waited? Because I have, on more than one
occasion, when they offered that service.

And *he* told me matching pairs referred to the woodwork.

** Got a tape recording of that have you too ???

See above.

Wonder what it is about this group that attracts some of the rudest
people on the net?
