Quad 63 Repair Kit

Deserves to be fixed. A true legend.

The Quad 63 is an excellent loudspeaker but early models have now reached an age where they can become temperamental. The Quad 63 repair kit has been designed to address the most common issues found with faulty ESL panels, namely, low or distorted output from one or both speakers and strange noises such as hissing, clicking, popping etc.

Our Quad 63 repair kit contains all you will need to rectify these problems. There are sufficient materials to repair a pair of speakers and have material left over.

The repair is straightforward and requires normal handyman skills. The kit contains comprehensive instructions, which are normally e-mailed to you. Instructions can also be supplied on CD ROM if required.

The most common problems encountered with the Quad 63, 988, 989, 2805, 2905 etc are, failure of the adhesive bonding the stator to its support matrix, diaphragm split along the suspended edge or failure of the adhesive bonding the diaphragm to the ESL panel.

Double sided tape is now supplied to attach the dust cover to the frame.


In addition to the above issues, the Quad 2912 also suffers a diaphragm problem where a myriad of tiny tears occur in the diaphragm and slowly grow large enough to cause discharge of the polarising voltage, e.g. hissing, clicking, popping noises.

All of these conditions are addressed with the repair kit above.
