Quad ESL 63 repair
Graham D
63s. Both work, but one of them produces quite a loud hissing noise
from the right hand side.
Do you know the nature of this problem? A damaged panel? An electrical
fault?
I bought the speakers at an auction and I think they were handled quite
roughly in the days before the sale. Could this have damaged them in
some way? There is no physical sign of damage on the cabinet.
An indication of the cost of any repairs (UK) would be very useful as
well.
Many thanks

same
hissing noise with your system. I am presuming that you have swapped the
left and right channels of your amp output and the noise remains in the
same channel?
As to the cause: I can't say from what you have described.

A bad EHT block is usually the cause of hissing Quads.

The hissing noise is specific to the speaker in question - and
continues even if the amplifier is switched off. There is also some
degradation in bass quality on the affected speaker, with louder low-
frequency sound making a sort of buzzing noise.
Kind regards,

due to excessive humidity in your listening room (the Quad is engineering to
work
primarily in low-humidity areas, as the manual explicitly warns).
I used to have the problem many years ago (10 years ago, in fact), but since
then I have only used the Quads in air-conditioned houses and never heard
the problem again.

Yes, Quad, a British company, engineered the speakers to work
primarily in low-humidity areas like Britain, known for it's
low-humidity, where it has low-humidity fog and low-humidity
drizzle.
If it's hissing, it has a high-voltage leakage problem and you
need to find out why and get it fixed. It is NOT a normal
comdition, humidity be damned.
Sorry, but Quad is NOT Lucas, whose products are notorious for
failing on days when the relative humidity exceeds 0%.

very occasional soft popping sound now and then when they aren't being used. When playing music there are no extraneous sounds.
If I were you I'd unplug the power to the transformers and take a look inside and make sure all the wiring is connected properly and
nothing is loose. If there are any fuses in the transformer units check to make sure that they are 100% ok. If after you check all
the wiring and nothing is wrong, inspect the panels to ensure that there are no punctures in the membranes. Be sure to discharge
the electricity in the panels before poking around inside the transformer units. I know that in my Acoustat's you take the red lead
and ground it to the tranformer unit case. The voltages for charging electrostatics can be extremely hazardous (around 800 volts I
vaguely remember).

Have you asked http://www.quad-hifi.co.uk/service.htm
I recently got a quite reasonable quote for repairing my 66CD player,
but they could not help with panels for my esl-57s.
What is a guide price for s/h ESL63s? OR maybe I should just start
saving for a pair od 988s - by the time I have the money they have have
some spare production.
