Behringer GMX212 PS ?

No...I am just suggesting you read through the complete thread before you spend your money.

I have read it! But between the pin of the output of the transformer there is a 0V voltage. And at the input X3 of the midi card, there should be a ~30V AC and there is nothing! Is it necessary to go further ? You don't believe it's the transformer? The fail happened when I had plugged RCA jack into the TAPE IN input, and the RCA jack was linked to my computer. Someone told me that I could cause a diffential current, due to the fact that the ground of the computer isn't the transformer's. Because the transformer is isolated. So it could bring a 110V differential voltage..? Do you know this fact?

[gtrplayr1976]

I didn't read any voltage on X3 either, but I did read it on the diodes, and between pins 1 ,and 4 on one of the 3886s which was 70v.

[sijobarteam]

Nothing between 1 and 4 of the 3886, and 0.13V on the diodes.

[gtrplayr1976]

Let me know if the transformer does it.

[sijobarteam]

I hope so, because I have bought it 52€ in Deutchland. I have to precise that me nothing happen when I turn on the amp. Even the screen, or the leds stay turned off. In your case the screen of the FX processor is turn on??

[gtrplayr1976]

yes, I just had no sound. Turned out to be just bad quality work. Had to resolder T4 ,and T5, and it works fine now.

[gtrplayr1976]

This may be a stupid question, but did you check the fuse ?

you sure it is a power supply issue? I have found that 99% of the time the issue with no output sound on the gmx212 a problem with the input jack, few the jack itself and some was the jack came loose and causeing the tiny plug to become unplugged.
