Has anyone tried my DAC-fix kit to see if it helps with this problem or not yet ? (lost track sorry!) No, I don't tried your DAC-fix kit yet. Is it difficult to apply it? Too much soldering? Unfortunately, I don't have an advanced skills with it. By the way... may you take a short recording of audi...

I have a new PSU now and fully recapped mainboard and the situation is MUCH better now! Constant high pitched whistling is gone and the audio output is overall cleaner. The first WAV in attachment is right after power on the STe, with real keyboard beep sound (to compare sound level with noise level...

That's very interesting to me. I have one more STe at home and it has the same problem. :O

Here is a normalized sample from my STe audio output recorded directly by audio cable. So, what do you think? Thanks very much. You have an enormous peak at 2600Hz, just as I do. Then you have one at 15.x kHz which is interference from the video output. The 2600Hz peak is really interesting. Maybe ...

Hmm, that's interesting. OK, I will record my "mess". Directly from STe audio output by cable, no microphone, no speakers, just directly to line input on my soundcard. Then I will normalize the wave and put it here. It looks that my motherboard is fully recapped (pictures are here: viewtop...

I'm almost 100% sure it comes from STE's audio output and it isn't the amplifier's hiss. I've tested it on two amplifiers with audiophilic cables, 0,5m long. I can record it and put it here as an attachment. It's about -40dB and it's some kind of whislitng, crackling or buzzing in both channels, not...

Hi. I would like to ask about the "STe DAC Audio Noise Fix". I've noticed a little "noise", "high hissing" or "whistling" in the audio output from my STe when the volume on my amp is a little bit higher. I saw a post about it at the forum here: "https://w...

I read somewhere few days ago, that this is for some voltage stability reason. I don't know if this is right or not.

Here are the pictures of my Atari STe motherboard.
