Quad Bulgin AC mains plug

[Mary Killebrew]

Rats,

Anyone know where i can get them in the US? Had to cannibalize my Quad
preamp so I could plug in the Quad II amps.

Also, does anyone have a schematic of the old ESL 57 audio transformer
circuitry? Sheldon Stokes has the newer one but I can't find the old one.
Thanks!

** "Farnell in One" have them in their catalogue, 313-968 - they have
a US sales branch.

** Same as the new one minus the high pass filter ( 2x 560 pF and 270 K
ohms ) feeding the treble panels ( brown wires) .

Sorry but that's the wrong plug. The Quad II uses a flat 2 pin Mains plug
which is NLA from Farnell or anyone else.Quad don't have any either as I
bought up all their stock of these a while back.
I'd recommend buying up a few more QC2 Mono control units as junkers and
pirate the parts off them.. They use quite a few parts which are common to
the 22 Control Unit - e.g. all knobs (except Vol. control); Mains plug &
socket(also used on the Quad II). The power outlets for the Tuners can be
re-used on the 22 as well.

** You are quite correct - the Quad ESL57 uses a Bulgin 3 pin plug, the
large version, 22mm dia.

which is NLA from Farnell or anyone else.

** Was it even a Bulgin one at all ??

The AC inlet on my ( lone) Quad Mk II has been swapped for a 3 pin mains
XLR type - just a bit a chassis filing needed to make one fit.

Quad don't have any either as I

** What a cruel fate .......

Seems it wouldn't be beyond someone with a lathe and a Palmgren mill
attachment to make molds...or they could be EDM'd from an
original-there's probably a reasonable market for them. I would replace
the connector before parting out an old box for one. I don't think an
XLR is appropriate for mains voltages however. A PowerCon perhaps?

** Sure - sell maybe 20 a year.

* The Cannon XLR-LNE series were designed for AC power use.

5 amp rating, shrouded pins, quite incompatible physically with other
XLRs.

Well, the plug says "Bulgin" on it....

Yes - definitely Bulgin. I've still got about 2 dozen or so spares but I
ain't parting with them as I regularly repair quite a few Quads & sometimes
have to fit one for a customer. Sooner or later they will run out.
Farnell & RS used to carry them as stock items up to as recently as about 4
years ago - if my memory is correct.
As the Quad mono control units are relatively plentiful - they are a useful
source of spares.

You are right there are a bunch of XLR connectors, however, "XLR"
without modifiers in the audio world is usually assumed to be the
common three pin small signal version. There are people out there who
will use these inappropriately! Plus which, at least in the US, they
are rare. Neutrik is a growth company and their PowerCon has big
advantages over IEC, so if in doubt that might be the best way to go.
However the XLRs designed for power are probably fine.

** I think you are alluding to this comment:

" The AC inlet on my ( lone) Quad Mk II has been swapped for a 3 pin mains

Errrr - see the words " .... 3 pin mains XLR type " ???????

The particular connector is commonly referred to as a "Cannon mains plug ".

BTW

Neutrik also made a similar and **compatible** series of connectors to the
Cannon XLR-LNE series.

** That is why I was careful to put the word "mains" in front of XLR.

** In this case a PowerCon is much to large to fit in lieu of the original.
