Good day all.
Firstly, happy belated 2025 to you all.
Need soem advice pls. My Numark mixer, after many years of faithfull service has developed a buzz. Literally just happend a few days ago. Even with nothign connected, no input signal, no speakers, nothing. Only plugged into the mains, and with switch on, I hear a kinda high pitched buzz right by the transformer.
I suspect a transformer issue, but not able to say exactly.
Any help would be appreciated. Thanx

Failed caps in the power supply is a good possibility, are you equipped to do electronics repairs? If not seek out a repair shop/guy.
Im equipped yes. Looked at them and they seemed fine. I guess it wouldnt hurt to change them. Thanx for the info.
looking at parts is good but not all faults are visually apparent...
and conanski's advice is sage, looking at the supply is 100% correct but i'd be looking for a bad diode in the rectifier bridge or faulty solder joints there.
