hi,
I own a Pro-Ject DAC box USB since many years ago. I know it is old and cheap, but it is also very small, still looks great, and does everything I need (I also use it as a sort of preamp to switch between sources), so no need at all to "upgrade" (and generate more junk we don't need on planet Earth ;)

Well, the problem is that the original 9V 1A ac/cd adaptor desintegrated. No kidding, literally, every time I touched it a piece of plastic felt apart from it. Then I bought one from aliexpress that looked identical, but when turning the volume up with no signal I can hear like electronic noises, something like an old fax machine, but more regular...

I want to fix this and continue using my little Austrian black box....

Because of the background of the story I suspect the noise is due to the new power supply, but I am open to any other suggestions.

So the question is, can anyone recommend a cheap adaptor that might help me solve this issue or any other solution?

PS: Please note I am trying to fix a machine that costed ca. 100eur around 10 years ago, not willing to spend 200eur in a psu

Thanks,
They offer one at 9v. Will try to get one and give it a try to see if the noises disappear. Forgot to mention: Curiously the problem is only in one channel.
