The quality of the GB PCB was pretty bad too.

Are they using felt as the dust cover?

I really like to try to make some wire stators for my DIY electrostatic headphones. I've bought some wire mesh, but I have no idea how to stretch it so that it's absolutely flat and tight. Any ideas?

Happy birthday!

I’ve used something similar with one of my headphones for a while now. It’s been OK. Yes, it’s not double insulated and it’s not as soft as the Koss cable.

Finish a new pair of electrostatic headphones today.

Congrats!

It’s funny that the size of the transducer is exactly the same as my DIY headphones - 120mm x 90mm.

This is my version - 3D printed using ABS filament.

Happy birthday, Kerry!

When I went and bought, I didn’t check the differences in price and quality. It’s what’s available in my area and I needed it quickly.

I use SCT3080KLGC11 in my Grounded Grid power supply and it works well.

Happy birthday, Kevin!

Thanks, Todd.

Wow! Very nice!

Thanks for all the good advices. I change the air nozzle to a bigger one so that it has slower air velocity, and set the temperature to a bit higher, and now it goes a lot better. I still have a long way to go though. By the way, the smell of the flux is really bad. Do you guys wear a mask or use a filter fan when doing the hot air soldering?

Wow! I tried to solder some SMD resistors today using solder paste and hot air. It’s so difficult! I turned the air down to the minimum already, but as soon as the solder started to melt the resistor got blown away. Is there any good tip for a beginner?

How much smaller are these boards compared to the originals?

Be very careful with the disassembling. The dust cover is extremely fragile.

Went over to a friend’s house and made a pair of field coil loudspeakers over the weekend. They sound surprisingly nice!

Sorry for your loss, Jose.

Sorry for your loss, Jeff.

Build a KGST. It won’t cost much more, but it’ll be much better.

Are those DIY headphones?

Happy birthday, Kerry!
