Hello everybody,
My son has a malfunction on his Yamaha Pianocraft R840 amp module, aged around 5 years; one channel is buzzing, a friend of mine told who has knowledges in electronics me that it sounds like half of push-pull amp is out.
Mys daughter who has some kind of same model had same kind of same trouble a few years ago and I red that this could happen quite often on that sort of equipment, as " usual suspects".
Does anyone know what could I do to repair? changing some pieces or even the entire board (if it is affordable of course).
Thanks for your suggestions.
