Hi Arno,

Nice to hear that you're progressing with your DIY headphones and amps. I highly recommend any of Dr. Gilmore's amp. I have not tried CFA yet, but I have a KGSSHV Carbon which sounds fabulous. Or if you prefer tubes, KG Grounded Grid is basically a tube version of KGSSHV Carbon. It's very nice too. I also have a KGST which uses small 6S4A tubes. It's easy to build and sounds fabulous as well.

I would not go for the Tubecad if you want to get out maximum from the headphones. This amplifier have significant roll-off before 20kHz. If you want relatively simple tube amp, you can try SRX+ from JimL.

Anyway, I am just finishing my last project.

Thanks gents for the recommendations. It seems Kevin Gilmores website is no longer up and while I tried really hard to find a mirror, I couldn't. It would be a shame to loose all the information that he provided over the years. I suppose I can get the schematics and boards for the KGST from Spritzer or am I missing something?

And on a slightly unrelated note, I stumbled across the two capacitor paradox today, which is an easy read in between if you are not familiar with it.

Hi Arno,

All the infos on KG's Amps are still out there. The link has been updated. Please check your PM.

Bonjour tout le monde.
Je suis à la recherche de plans cotés des deux prises Stax.
Impossible de les retrouver aujourd'hui.
Les liens de Kévin Gilmore ne fonctionnent plus
Une aide s'il vous plaît.

I have the 3d drawing of the socket. You can 3D print out using ABS filament: https://www.tinkercad.com/things/l59XfzK35qP

I can't read the drawing with my little phone.Is it possible to have a drawing with measurments please ?
This one is for stax pro headphones,but where can i have the oldest (6 pins),please ?
Otherwise no 3d printer ,but miling,driling and lathe machine.
Regards

Sorry, it’s been a long time and I don’t have the measurements anymore.

Désolé, cela fait longtemps et je n'ai plus les mesures.

Merci dans tous les cas pour votre réponse.
J'essaierai d'utiliser vos fichiers avec un ordinateur plus tard.

Hello everyone. I have been reading the thread over the last couple of weeks and damn, there is a lot of information to take in. I have started to design my own estats after being influenced by chinsettawong's work and that of everyone else that has followed. I have spoken with several members who have been very helpful with general orientation and answering some questions. So over the course of the following months I'll be posting pictures and updates of the process once I am done with my KGST. Thus far, I have ordered 3 micron mylar, staticide 6500, and have started playing around with CAD. My first design is going to be round, as doing everything round is much easier than oval shapes like the orpheus clone. Active area will be 80mm. I'll be posting images shortly. My second project is going to be something like an L700 plus, with oval and quite tall drivers (still figuring out possible dimensions)

As far as cable goes, I am probably going to use the Koss extension but I have a question regarding the wiring to the headphones. Has anyone used mini XLR or MrSpeakers conectors as a possible detachable solution? I remember reading about a MK1 L700 mod a while back, and now that STAX has started going detachable with it's MKII's, I wonder if there is any experience with any of these connectors? Thanks every one for all the information shared.

Best regards

This is version 1. Still missing some details, as this is a rough sketch.
Inner diameter 80mm
Outer diameter 95cm
2mm holes with 1 mm spacing
63% open area.

The stators I am probably going to have done by pcbway in 1mm double sided FR4. Spacers will be 0.5mm single sided FR4.
Would there be any benefit in going double sided FR4 for the spacers?

Best regards

 

[chinsettawong]

Hi DrBiehl,
Your design looks good. I also use single sided FR4 as the spacers. I don’t see any advantage of using double sided one for the spacers at all.

Version 2. These are 120x90 ovals. Active area is 105x75mm. Still rough sketches. The idea with this design is to do a sort of big lambda driver into a Stax looking enclosure, akin to the SoCas CanMod for the lambda series. Version 1 will be more like omegas.

I couldn't find any info regarding detachable cables on DIY builds so I'll give it a go and report back. It seems there are some 600V mini XLRs that could do the trick.

Ended up going for a massive round shape. Active area will be 90mm in diameter, total width of driver is 110. The housing design is done as well. I will be using 110mm AKG pads. This gives the greatest surface area for all of the designs I have tried so far, even more than the 105x75 oval. I am considering using 0.6mm spacers since the driver is actually very wide.
