  1. Have you got the way to align them? Actually it's very easy. You select the objects you want to align. Then you click on the align button on top of the screen. You'll then see the black dots with lines on your parts. Click on those dots and your parts will be align accordingly.
  2. I use tinkercad from time to time to design some simple things. But I’m not an expert.
  3. The easiest way to confirm the problem is that you try someway to ground the amp. If the hum goes away, then it's the amp. If the hum doesn't go away, then it's the headphones. By the way, did you recoat the diaphragms?
  4. I also have hum problems on my amps. In my bed room, there is no actual ground connection. So, I just live with that little hum. Also, please check to see if the problem is from the volume attenuator. On one of my amps, turning the volume knob back and forth changes the hum. At a certain volume level, the hum would go away completely.
  5. Hi plaurids, If you touch the the ground pole in the rear of the energizer and the hum disappears, then it's most likely that the hum is from the energizer itself. In my experience, some headphones can be more sensitive to hum than the others. It has something to do with the coating material of the diaphragms. If the coating material on the diaphragm has a low resistance, then it can make the phones hum more easily.
  6. Meeting with Purk and his friend, Wut. Unfortunately, nothing new to show to them. But, as usual, we went out for a lunch together, and I had to make sure that I fed them enough. 😆
  7. Is that a stepper motor connected to the volume pot?
  8. Yea, just let’s open the driver and see how it is inside. If there is mold, can we clean it? If the diaphragm is bad, I can help you make a pair of new diaphragms. First, you want to unsolder all the wires. Unscrew all the screws and it’s open. Please be very careful with the dust cover as it’s very fragile. Take some pictures and let’s see how bad it is.
  9. Hi plaurids, Fixing the headphones, if the membrane is still in good condition, isn't that difficult. If you are handy enough, I can guide you. Wachara C.
  10. Very nice! How do you stretch the diaphragm by hand? Do you have a scale or something to help you tension each side of the diaphragm to the same tension?
  11. Do you have other headphones to test and confirm that the issue is really from the amp?
  12. I've been searching for some DN2540 to fix my KGSSHV Carbon but can't find them anywhere? Do you guys know of anywhere I can get them? Or can I substitute them with the small current version in TO-92 package?
  13. Have you ever thought of using fiberglass or carbon fiber as the mesh holder?
  14. Do you hand solder or use hot air to solder the SMD components?
  15. That's such a neat idea. Can you show us the bottom side how you hard wired them together?
  16. Sorry, you’re wrong. The case is made by one of my DIY friends here in Thailand. It’s teakwood, and I spray the top aluminum cover with black paint. The amp inside is KGST.
  17. @purkcame to visit me today. I showed him all of my DIY headphones. He seemed to like my Omega clone the most.
  18. Very interesting! I am very curious to learn about your coating. Where do you buy it from?
