Newly developed ground loop hum in a Stax SR-007A's right channel
chinsettawong replied to plaurids's topic in Headphones
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? -

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. -

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. -

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. 😆

Is that a stepper motor connected to the volume pot? -
Hints on maintaining / improving my Stax SRM-T1S
chinsettawong replied to plaurids's topic in Headphone Amplification
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.- 104 replies

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.- 104 replies

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?

Static-like Sound Coming from Left Channel?
chinsettawong replied to ThePhoenix's topic in Headphone Amplification
Do you have other headphones to test and confirm that the issue is really from the amp?
