This one IS the real deal.


** Thanks for that schem link - far easier to read an interpret than that
horrible re-drawn one.

The particular Quad 33 in question was picked up recently from the USA via
eBay by a friend of mine.

The only defects found were a missing fuse top ( by luck I had the exact one
needed on hand ) the use of a US 2 pin plug on the AC lead and a few
slightly noisy switches and balance pot.

Plus the internal tranny was linked for 127 volts AC - contrary to the eBay
blurb !

BTW

Quad 33s are very "green", drawing only 1.6 watts of AC power and most of
that is used to operate the dial light !!

Its very worthwhile changing the capacitors at that age, the original
cap makers weren't much cop!.

IIRC somewhere there is a mod to -improve- the power supply, bigger
cap/s there too I think, and I don't reckon it'd have PW doing
16 2/3 RPM either..
