Unusual request, I know. But I thought I would give it a try. Does anyone have a replacement voice-coil planar assembly for a Stage Accompany SA 8535 planar tweeter? Hey, it's a new year. You never know...
Thanks!
Thanks!
Refurbished SA 8535's
Hi Nyatt,
I will be undertaking a refurbishing project in the next few days for as many as [8] SA 8535's pulled from retired Entertainer E24's. There may be some replacement diaphragms included in the octet, but I anticipate maybe needing to order some more from Denmark, or scrounging them elsewhere. Stage Accompany has gone through some permutations, as first they ceased operation, then came out under a new name to support customers by specifically making replacement RCD diaphragms available, and now SA is back, along with an announcement they are selling SA 8520 diaphragms.

When I get a line on some replacements, shall I keep you in the loop?
By the way, replacing them sounds simple, but in reality it is extraordinarily difficult, as many frames have had their neodymium magnet encapsulation fail, causing peeling and obstruction of the narrow gap that the diaphragm frame slides into. I have a planned method to improve the process.
BTW, after the tweeters are inspected, tested, and serviced as needed, they will be for sale.

Thanks for the reply. I would appreciate being in the loop. Much appreciated. And I started to disassemble one tweeter, and found exactly what you are describing. Which makes me wonder how much I want effort and $$ I want to put in these. But they sure sound great.
I am actively working on sourcing the diaphragms. I visited the "pile" of SA 8535 parts I will be re-manufacturing today. Some are still in E24 cabinets, and others are loose in a box, but the sum total of them are on two pallets perched upon the top rack shelf, so its going to be a couple of days before I retrieve and assess them.
I don't currently know how many diaphragms I need yet. Perhaps if we end up buying 6 or more at once, we can request the best possible pricing.

Still interested. Shipping and quoted cost were prohibitive when I checked back in May, 16.

Hey, when you got the 8535 units, did you get any spare waveguides? If you have a single, would you be up for selling it? I would be interested. Thanks!
I probably have two SA 8535 chassis with ribbons that have been dorked with - the previous owner modified them by trying to solder directly to the solder connections on the ribbon itself - a no-no.
Also one has peeling magnet coating - which to me looks like graphite CRT coating, fwiw.
Haven't looked at them in some time, so my description is probably about right, but may be at slight variance with reality...
Likely would sell as-is, since I will never have time to play with them.
As far as waveguides, nyatt, I'd build my own, the originals are rather "non-flat" in resulting frequency response. They are more or less "manta-ray" type conic horn sections.
