Thought I should read all the posts before I asked any dumb questions. A few days and over 3800 messages later, here I am.
Congrats and thank you, Chinsettawong, on sticking around and continuing to innovate and educate about these homemade Endgames.
I'm just an audio and electronics hobbiest that's mostly worked on and made some vacuum tube equipment. The best I've got - and heard of headphones, is only the Hifiman 400i, so hopefully I'm in for a good surprise if things work out.
So far, I've been just doing small experiments using graphite rubbed cling wrap and 0.5mm card spacers with metal speaker grille mesh as the the stators. It sounds pretty decent (for what it is) running off a pair of 70v to 8ohm transformers in reverse, for a 90:1 step up ratio. Being lazy, I sacrificed a disused bug zapper for 500v bias, with an extra 22meg in series for some semblance of safety.
I attempted a design using metal mesh like was recently suggested after seeing the the Stax and Hifiman Shangri-la, by gluing the mesh to a sturdier backing to keep it mostly parallel, but it was fairly quiet due to slight warping away from the diaphragm, and the larger 80mm active size made the card spacers even more lacking in stiffness and insulation.
So far, it seems that I need to make a deal with someone local with CNC and 3D printing capability, and to suck it up and build a proper version of the KGSS amp.
You most recent float design looks great, Chinsettawong, and if I can find some help, I'd love to provide a second opinion on how it sounds.
