Very nice build!

Really nice work Kerry. You really amaze me everytime I see your build. Happy New Year! Wachara C.

Happy New Year!

Merry Christmas!

I'm sorry to hear about the terrible accident. My prayer to you and your daughter for a speedy recovery.

Wow! Nice!

Very beautiful work Kerry!

The R40 and R41 are indeed identical. I replace both with new resistors and now the amp is back to singing. The root of the problem is that my PS has gone bad and put out 24VDC instead of 12VDC. Somehow the excessive voltage only destroys one of the caps and R40. Thanks Kevin and Birgir for your help. Wachara C.

Hi Birgir, Do you think that R40 and R41 could be the same value? I search pictures on Google and found a shot you made long ago.

Gentlemen! Please help me fix my SRM252A. One of the 4 250V, 22uF capacitors is leaky. I've already replaced it. The resistor, R40 (near the transformer), is burnt so bad that can't tell its value. Does anybody have its schematic diagram? Wachara C.

Nice build Birgir. I really like your small regulated PS board. Wachara C.

That's a very beautiful build, Chiguy.

To check for imbalance I would check the wires and their connections first. Then if the problem still persists, I would recoat the diaphragm.

Wow, I really like that amp, Birgir.

I agree with Spritzer that all you'll have to do is to open it up to clean it.

Nice work s_r.

Wow! Nice! Are you using T2 PSU for the KGST?

Stax adds thin Mylar spacers to increase the spacer thickness in an SR007 MK2. I'm pretty sure that they do the same on SR009.

I bought a pair of SR009 a few months ago, and I noticed that the phones weren't as sensitive as the pair I heard when they first came out. I think Stax might have increased the spacer thickness just a little.

Happy Birthday!

Oh, I'm sorry. I didn't know that they're hybrid headphones. I'm not sure how to make them sing together now.

I have no idea. But, I think you can convert them into electrostatic.

I like 3 microns Mylar, but anything from 1 to 3 microns should sound wonderful. You'll have to give them a few trials and errors on diaphragm tension before you are happy with the sound though. By the way, those drivers look nice. What is the inner diameter of the spacer holding the diaphragm?

Electret drivers use different diaphragm from electrostatic. Coating them with what you use on electrostaic won't help.

Beautiful!
