looking for Quad 63 interface...

[moray james]

a friend recently gave me an interface for a Quad ESL 63. The speaker had damaged panels. I would like to find a match for this interface. The long trem plan will be to build a vertical line source with horizontal segmentations. Anybody got one or a pair of dead 63's with working interfaces?

Sorry I can't specifically help.

But just the other day I thought about a line array that would use a delay ladder(?). Wouldn't it be straightforward to figure out and string together the correct inductors necessary for the specific drivers you're using?

I don't know....

Peter walker spent 17 years getting the 63 ready to go to market. In any event this is a faster way to build one, the panels I can do. Keep your eyes open for me. Thanks.

It's not the cheapest option, but you could call QS&D and get one I'd bet.

Moray,

The schematic is shown in Borwick's book, "Headphone & something or other handbook". I put a link to it recently the Blowtorch thread in Solid State... I got a copy out of my library some years back.

I'd go for building my own, if I was using my own segmented cells, since the Quad is set for specific spacing... If you've seen the innards of them, they're full of big copper coils wound with scary thin wire... fwiw.
