Well well, it seems I can't order that foil, there is no option for Finland in checkout...tens of countries, but not Finland and not Sweden either...Norway there is...strange!
Strange when they have this page: Grainger Global Shipping International - Global Export MRO - Grainger Industrial Supply
When I go to check out, many countries disapear.

And when I try to order those Scalloped Aluminum Tubes from DRB, they cost about $30 but there is a fee "Flat Rate - Addition Charges May Apply to Oversize Items $60.00"... costly it begins to be...
So any of you guys making progress on panels so far ?
Just happened to pick up some 1 ohm Scintillas locally
Was able to retension and realign all tweeters and mids to factory specs. They were all slightly stretched although when vertical appeared ok.
Made an adjustable arm with a roller and fishing line taped to each ribbon and a specific gram weight for both types
And the bass panels were installed I believe in 2007 thereabouts at True Sound works with new bass panels.
It might be possible to save these for now as they had some shipping ripples and a slight break that might not affect performance but in the end will probably make new panels for these also
Thinking about a CNC waterjet cutting template this time around...
One thing I noticed is an asymmetrical crease to these bass panels , the outward bow is wider than the downward crease suggesting maybe the outside roller might be pressing on a soft rubber surface roller or maybe not even a roller at all, not sure.
So how goes it ?

Finding working Scintillas I had always assumed was hard work. Finding them locally is amazing luck. I'd love a pair, just worry how much power they eat! Let us know how they sound.
Is that the pair in Fountain Valley advertised as a project? They were moved, damaged, sent to True Sound Works but rejected due to rotted frames.
Yes but the damaged external cover was remade and all the internals , MDF chassis magnet structure , etc was undamaged with new bass panels installed that got lightly rippled because of a move.
A basket case to some is a gold mine to others.

That ad described them as below for $1200. If you paid close to that, I don't think the frames are good.
"Got several great years out of them, then they ended up in storage due to baby. Movers didn't handle them right and caused the woofer panels to get warps / dings. This caused a rattling sound.
Sent them to True Sound works for new woofer panels to be installed. Wouldn't do it w/out a full new frame being built as the diagnosis is that the original particle board was rotting away.
A fun project speaker that I'm willing to let go for cheap. You could have some DIY fun with them, or send them to true sound works for a full re-do."

No , again , there is no rotting of the 1” internal chassis mdf on either speaker.
Were these built with the fine grain MDF we see today? No , this is the courser grain structure
Fiber board with a rough edge structure. No swelling or cracks anywhere
Just a cheaper grade but no issues
The Diva chassis frame (3/4”) has the dense fine grain MDF we see today and would have been the better choice on the Scintilla ,yes

Panel peeled off rather easy with no broken traces and the foam was in good shape with no signs of fatigue.
Panel is .0025”
All this talk of Scintillas...I have a pair needing work and a set of replacement bass panels from Patrick that I have yet to open... the more I listen to my recently refurbed Quads the less I look forward to that Scintilla project....anyone want to buy the 1 ohm panels from me? They were around $1300 when purchased a few years back....
If you can ship them to Finland but maybe it would be too expensive. If you were inside EU, then it would be a different story...
I was looking into purchasing a pair of Scintillas for a rebuild and contacted Florian Wiegand for ribbons/panels. Looking at his offerings versus Patrick's, and the history behind Patrick, I am convinced Flo's product is superior.
He works together with Clarisys Audio and acts as a distributor. He also supplies copper returns as an upgrade of aluminium, which can also be soldered much more easily. Products ship very well packaged from Vietnam (because of Covid-19) and he has bought over 20 sets of ribbons so far and never had any problems.

Wow, looks like I paid quite a bit more than that price (pair)...I still have to get the Scintilla Foil mid and tweeters, the ones that I have are functional, but look horrible...
Maybe the currency exchange rate was NOT in my favor when I bought them...donno
You can probably get them direct from Patrick for much cheaper than what I paid for mine...

John , you can retension all the ribbons with a simple roller setup and a gram scale if they are in decent shape.
Each tweeter to not exceed 40 grams and the 1.950” mid no more than 60 grams
Factory used 5mm sag
You can see before and after results
Never expose these ribbons to a windy environment such as near an outside door or window drafts

I think I read somewhere that Diva's midrange (with kaptonback) tension should be 125gr (could it be so much!). So perhaps pure aluminum tweeter ribbon is similar with Scintilla, around 30-40gr. I'm not sure, but have a hunch...
