Quad ESL63 Restoration - dustcover frame

Hi,
I am restoring a beat up and messed with late model ESL63. The panels and electronics are fine and I have successfully finished 1 speaker.
However one speaker is missing all the dust cover frame pieces. The rest of the frame is in poor condition. The plastic base where the extruded Aluminium side pieces are screwed in have broken on both sides. The grill cloth is missing.

I will hunt around for hard rubber or plastic "C" section strips and possibly glue them to hard plastic strips to try and recreate the original. I am not sure if I can source the bits locally and if they would hold on firmly enough under tension.

I am hoping someone has found a solution or can think of a suggestion.
Thanks,
Kffern
 
Reach out to the ebayer who often sells quad parts in the UK. He has all sorts of parts, and can most likely hook you up with the plastic pieces. I don't have any to spare or I'd help you out.

Also you can inquire with the importer (not sure who it is in the land down under), I'm pretty sure those plastic extrusions haven't changed over the various models.

No. Those are the grills. They look a lot better than the originals. I'm sure I could find plastic grid exactly like that locally though.

The dust covers are mylar which is glued onto plastic "I-C" shaped plastic strips. The "C" part snaps over the round edge of the frame, which is an aluminium extrusion. ER audio sell the dust cover mylar and 2 way tape which I have bought. From what I have read they don't last long without the dust covers. With my 2 dogs probably even less.

Thanks Sheldon, I was waiting for your response.

I wish I was able to help out more. I checked my supplies and I don't have any of those plastic frame pieces. I've bought frame parts from the ebay person, and have most things for the 63's, but not those plastic pieces.

I looked at the 2812 service manual and the exploded view shows the parts you need, but they are not called out on the BOM. So even if you talk to the importer, it might take a bit of work to get them to get you the correct parts. I was hoping to find a part number for you but I have failed.

Also the little corner brackets that hold the four plastic pieces into a rectangle aren't even shown on the exploded diagram.


Here's the ebay guy you may want to talk to:

Hi Sheldon, The set I have was missing a few of the connector pieces but I cut a few out of some thin steel I had lying around. They are a bit tight but should work. I emailed Quad UK and waiting for a reply. I could see myself being put on hold a lot if I called. Same for the Australian importer. If they are like most of the local importers I wont get far anyway.

Have you had to deal with broken plastic base plates? seems to be a common occurrence. Rob has a couple with the same problem. Moving the speakers while they are on the ground seems to be the problem. Rubber feet wont help.
Thanks,

The only time I have problems with broken bases is courtesy of UPS or FedEx. I generally buy spares on ebay when they show up (one is up there now that I need to buy). I am repeatedly surprised at the level of abuse things take by the shipping services. The OEM quad boxes are no longer enough to keep the speakers safe.

QUAD Musikwiedergabe do have them along with the plastic base. Works out to quite a lot and I havent got the shipping price as yet.

Sheldon, I bought some Spandex material and made a 84cm diameter sock. Its a fairly tight fit and I had planned on fixing it to the base of the wood and then screwing an oak trim around the edge of the wood. The top would be as the original. Can you see any issues with this? The picture shows how I fitted the aluminium plates to the underside of the base wood panel. The previous owner had put screws through the wood on one side. You can see the missing edges of the plastic base plate which I need to fill.
Regards,

Ah, the plastic base you are talking about is different. You are talking about the bottom piece of the panel assembly. I thought you were talking about the speaker base or plinth that houses the electronics. Yes, the corners of those end pieces break when they are roughly shipped. It doesn't help that the metal vertical pieces are held to these plastic end plates using flat head screws which pre-stress that plastic in tension and get it that much closer to yielding when the speakers in their boxes are dropped. Those should be pan-head fasteners with counterbores instead and molded in alignment features.

Yes, I have those parts, but not many of them. Let me know if your other deal is too expensive for your taste. Still can't help you with the dust cover frames though

I would say, buy something like this for parts and you'll be set.
Never seen the plastic bottom and top parts, nor the plastic dust cover rails for sale as parts. A plinth maybe, but that is all.
You could ask the seller to take the speakers apart and only ship the parts you need and/or want and leave the large parts (like the grills).

They are in much better condition than the ones I bought. Mine were missing the top wood panels as well. They are a late model 63 which I think has better electronics possibly. I paid a bit less but after everything it will come to close to A$1000 I guess. He should be able to sell them whole in the USA.

Good buy!
Mine wasn't much less and it was wrecked. The guy had cold punched the slots in the uprights to hold the grill in.
Luckily Rob had the wood tops. The grills are dented and battered. Not sure if they will go back.
Might get the dust cover frame from China via the importer.

If I understand that correctly, the slots that hold the grilles on either side were collapsed at the top and bottom? If that's true, that is from Arcici stands. Those things suck and damage the grille cloth and the speaker frames as you have seen. The guy who designed those isn't qualified to pet my dog.
