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.

The boards you have are the GRHV PSU, different from the KGSSHV PSU. The 600 R resistor and the CPC1117N are there for those that want to implement a timed delay for the HV (for the amps using tube output like Blue Hawaii) You can simply leave them out if you don't need the delay function.
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.

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?
-
That's impressive!

Hello,
The previous owner of my SR-007 Mk2 headphones has had wrongly adjusted bias supply of a DIY KGSS for a short period of time (couple of days) and the diaphragms have arced several times (by loud pops) - based on his words. Is it possible to check the condition of the diaphragms from the outside without disassembling the drivers?
Thank you
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?

Happy birthday!

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.
