Witam, mam w/w głośnik w którym został podłączony omyłkowo zasilacz 12 v zamiast 9v,
uszkodzone zostały końcówki mocy : oznaczenie na układzie : XA9901,
prosiłbym o informację czy są jakieś zamienne układu, które można zamówić dostać u nas na rynku czy pozostaje tylko zamówienie z chin?

Hello!
Most likely, there is no equivalent substitute for this chip. You must use the original one.

Bezpośrednimi zamiennikami układu XA9901 są: MD8002A oraz TDA8541T. Nie patrzyłem za dostępnością w Polsce - to Twoje zadanie ;)

If I'm not mistaken the original chip XA9901 is disabled, when the CTRL (pin 1) is pulled to GND, which is just the opposite at the suggested replacements. The chips MD8002A and TDA8541T are enabled, when the pin 1 is pulled to GND.

Yes, you are right. Simple "signal inverter" will do the trick.
