i will this project is so much fun and so much possibilitys
yay first tests with 2µm Mylar are very promissing now i would like to put the testbench setup in a case so i can try it at home. somewhere here in the forum i saw that Wachara 3dprinted a Stax connector and not sure if he posted the stl file for those? and David milled them with the cnc? would love to build those myself hope you can point me to the files
I am glad the 2um Mylar is promising. You seem to be making good progress.
I do use a CNC to make my plugs, although earlier you wrote that you would not be using the Stax plug and socket.... although I think it is good if you do.
I mill from hardwood and plastic, depending on the plug I intend to use. The pins are from 3 pin XLR plug kits. Obviously you will need two plug kits and have one spare pin.
The spacing for milling was given by another Head-Fi user a while back on Wachara's thread, not sure how far back. I have just looked through my files and I have not saved it. I will look through my home PC and back through the thread to find the drawing. The holes for the pins are 2.5mm which provides a nice tight fit on the pin.
yeah david and the results i get with your test bench setup are by far better then i expected from this diy project pretty amazing also planing on buying a bigger cnc machine and i think its more clever to stick with an "standard" conecter if i might make one for friend who uses an stax amp... those xlr pins i have some good idea
and those are compatible with the original stax cabels?
Yep, the 3 pin XLR pins are the pins to make an exact fit on a Stax socket!
The results from the audio transformer energiser should be good. Just wait 'till you plug them into a tube or solid state energiser, you'll be even happier with the sound.
I have now found the pages and thread numbers in Wachara's thread for the plug details:
Page 60 - post 895
Page 102 - posts 1521 and 1529
This will show you lots of information on the plugs.
Here is the link to my Stax jack on tinkercad: https://www.tinkercad.com/things/l59XfzK35qP-stax-jack
You can download the 3D print file and do the 3d printing.
thx will try the 3d print and also mill a connector just need to buy some pins
MEHHHHHH didnt receive the Electrostatic Speaker Membrane Dupont Mylar C 3um 20M from ebay seller won the case even if the foil clearly didnt arrived at my place any other source? hmhmhmh
Sorry to hear your Mylar didn't arrive from the eBay seller, but glad you're still making electrostatics - not heard from you in a while.
The sellers that most use on eBay are one of two who advertise on eBay.COM from Taiwan. They use the normal logo picture of a guy holding stretched out Mylar.
Alternatively, you could use the seller www.indoorspecialties.com OR freeflightsupplies.co.uk/index.php/products/lightweight-covering-materials.
I haven't used either of these, but when I was writing the suppliers list, more than one person recommended each of them.
yeah sure im still on it from that link i got some foil but only 2um and 5um and they are not that wide with my tire strecher i cant use them need wider... and yeah i bought it from that ebay guy :/
They make and sell ESL kits too.
