Whether an audio amp uses switching p/s I don't know. I do know that feeding my amp from a (switching) convertor 12vdc to ___ ac will introduce so much noise the solution is unusable.
I would rely on the answer from Manufacturer's distributor / repair service
The model number of my Y. amplifier is MS60S, the part number of the 220/240 vac transformer I took out is XHO37, AO, JA 05B SMD 29.
Whether it fits inquirer's unit I do not know and do not plan to spend time on. The part is in proper condition, located in MX and available for u$50 packed for shipping. There are Fedex, UPS, DHL, and postal services available.Packed weight is <2 kg.
