Wow! Very, very nice!

I'm sorry, but what I meant to ask was did you have the driver's dimension?

Thanks for sharing those nice pictures. The driver looks so much like my JF clone drivers. Do you have its measurements?

Very nice build! Do you mean that you like the sound of GG better than BH?

What kind of stone is it? I kind of like the lava stone table top. It should be cheap there in Iceland.

Unless the diaphragm is stuck to one of the stators, hitting the headphones probably won’t help.

Interesting. I don't know how one can drill holes like that.

Take it apart and show us some inside pictures, please.

Have you tried resolder all the joints? If nothing helps, you might want to try recoating the diaphragm.

Happy belated birthday Birgir. Wish you could come to visit me in Bangkok someday.

Happy birthday!

Happy birthday!

Thank you so much for all your advices. I've finally fixed the problem. The C2M1000170 and 10M90S on my board have gone bad for some reasons. I replaced C2M1000170 with a SCT3080KLGC11 from a local store, and luckily it worked. I parallel the 5R with one more 5R, and now the power supply is working perfectly. The amp has been running for at least 2 hours with no problem. I couldn't have fixed it without your help, Kevin, Blueman2, and Soren. Thanks again.

The voltage was about 465V without load. Took out the 2n3904 and connected the amp board. Fired the amp up and the B+ became around -12V. Switched it off and the voltage gradually came up to around 45V then went down to 0. Can I try to change some R to increase the current limit a bit more instead of taking the 2n3904 out?

I need a little help here. When the amp is running, my B+ voltage keeps on swinging between 370-410V while B- is stable at 465V. Is my B+ supply running out of juice? What can I do to fix? I'm using this PS board.
