Out of interest, is this the kind of transformer you're referring to? Yes, but what is on the link is a low-cost solution positioned exclusively for voice (300-3.3 kHz). In the upper frequencies it works fine, in the middle - high distortion, in the low - "wow, what is it?". For low distortion (and …

To power the amplifier from the power of the computer, you need to break the ground loop. 1. Signal transformer. It is expensive. 2. A very competent engineer who understands PCB routing and low-level signals. They work for NASA or SpaceX. Such an engineer will cost even more than installing a …

pin 17 on RC5058 = 5,2V (same as my psu +5V line output) Sorry, lost in translation :-( It is worth measuring the voltages Vcpu, Vtt, V3.3V, V2.5V on the motherboard itself. But I won’t tell you the measurement points, I don’t have Abit. It may be worth looking in the direction of overheating - an …

Informative video, I didn't know those types of fans could be disassembled. Not all. On the video - non-separable, because the brass bushing is torn out.

Can I remove both halves without destroying it? Stick your all fingers between the turbine (yep, it's not a fan) and the base and push them in until the turbine pops out. Do not use tools, only fingers. Otherwise you will break impeller. like this video https://youtu.be/opB5Je1oqpA?t=59 Only at the …

For s754, I would look for something on VIA from Abit, Epox, DFI or Soltek. With replaced capacitors, of course. 90 watts is not 30 (like Tualatin), no Japanese capacitors will last 20 years with this power consumption. PS. I have a Jetway and it has a design flaw in the powering of the …
