    My DIY electrostatic headphones

    nice, very nice, thanks I haven't tried anywhere near as many things as you have So when it works I move on to the next problem only have 2um film staticide has worked for 2years on one set so guess its stable hole size didn't seem to make much difference I mostly copied your work adapted to...

    Those look nice! what is hole size and spacing? 1.5mm holes, offset spacing, 2.5mm on center? Gonna try having them made, I do double sided because they stay flat better and then only connect one side electrically that way the outside does not contribute to capacitance and coat the stator...

    Yea mostly building amps those are printed on a Tevo Tarantula, build area is 200mm cubic The headband just fits on the build plate. it was $200 and now they have a bigger one called Tornado and its much easier to assemble. Many Youtube videos on 3DPrinters, that's how I chose that one. its...

    That is after you learn to use them... :smile_phones: So I drew this up and printed some parts to tryout. will make some changes but it will work just fine. tried ABS but even at 50% infill it was very brittle so back to PLA for now as its very strong

    I looked for that cable also and the closest I could find is Cicoil, available from Digikey.   12kv rated High Flex flat cable...

    those are two year old pic's I mostly listen to ortho's and build amps. but they sound just fine and  use them  to test  new amps so far have not burnt any but that would be fixable   I found that other than diaphragm tension and coating the rest is not that important. OK active area...

    not sure what you mean but at first I used nylon screws but they are a pain..... then started using Polyphenylene Sulfide (PPS) washers, very high voltage, for transistors. example: SW-125-150 Avid makes them as well just pick the diameter and length you need to get through your stators...

    I use it for same reason, found on amazon. spray can of 6500. it works, none are easy for me to apply the right amount the first time...every time. one set have been working for a year so far.

        Those look Nice!       Today I tried UDPE and it does not machine nicely for me, very stringy or I am using the wrong bit. Want to try Delrin. also have been listening to the JFloat's and just can not seem to want to wear them :-) although except for low bass the do sound good...

    My DIY electrostatic headphones

      Yesterday / Today I looked for the floor cleaner.  As far as I can tell from the picture the ingredients are: Linear Alkyl benzene Sulphonate (LAS) and Sodium Lauryl Ether Sulfate    Which here in the USA manufacturers do not have to list the ingredients on the bottle.   Also there are...

    Well I could be completely wrong at this point, more soundstage is what I was expecting,  so not hearing that I chose the easy to source pad version. also mental bias towards what stax has done?   I can not find the exact products Wachara uses and am going to try some of what is here...

    yup only 2yrs 3mo preparing    well just holding them up to my ears they sound very similar. And all Good>>>>   when you account for diaphragm tension as some are tighter and  have less bass.   If I had to pick right now I would say the best is the lower middle black one with less open...

    yes that is what Spritzer said > so that is what mine is..   still wonder what more would be like.

    Yea I would not want to wind 7 6.3v filaments, 2 420v and a 16-0-16v. could it be done all in one?     Tonight every thing seems to be working... oh I started using the pps transistor washers from the KGSSHV so that I can use metal screws...   all these work,  wish I knew why  :-)  ...
