The picture could be from my thread on the other site. I remember I saw it sometime ago. Since the stators are not insulated and with too high volume played, the arc is very possible.
-
Wow. Those are pretty bad arc spots.
-
Could you take a lot of pictures to show the inside of the driver?

If you guys in Taiwan are interested in DIY electrostatic headphones, I can bring mine for you to try the next time I'm in Taiwan. 可能在明年四到五月.

我常去台灣.

Thank you Kevin.

I'm making a GG and will be using this GRHV board as well. How can I enable the time delay HV function? How long does it delay the HV to come up? Do I need other circuits to work together with this function?
-
PM Spritzer and kindly ask him to build you a Carbon.
-
Congratulations!

You might consider putting a thick coating of clear nail polish over the copper trace. It's a very good insulator.

I really feel that those perorated holes on the back covers of the headphones are too small.
-
Very nice and clean build!

Well, if the dust covers are not done right, they can affect the sound. In the early days, I made my dust covers as tight as the diaphragm, and those indeed affected the sound, especially the bass. On the newer headphones I make, I crumple the Mylar and only give it a light stretch to make the dust covers. And they don't make any difference in sound. I happen to own a pair of Martin Logan. I feel that the integration of their ESL and the subwoofer is not that great. I very much perfer my DIY Full range ESL.

The charging time of 20-30 mins can be a real problem. With a good coating, the diaphragms should charge up instantaneously.

Thank you Kevin and Birgir for your kind words. I'm so glad to hear.
-
Those look more like DIY headphones to me.

Happy birthday!

Hi Kevin, How do you connect a delay board to drive the high voltage switch in the current high voltage boards?
-
Hi JoaMat, How does it sound compares to T2? Do they sound very similar?

goldenreference low voltage power supply

That's impressive! -
Unfortunately, it's impossible to check the diaphragm without opening up the housing and disassembling the driver.
-
Thank you JoaMat.

I'm building the GG right now and I'm wondering what R current limiter I should use?
