Used B&W SA250 MkII subwoofer amplifier. Taken from a working system
In good used condition – there are a few small scratches but nothing major. I have tried to show them in the photographs
Stock photo has rack mount ears fitted which I do not have so won’t be supplied with amplifier. Amplifier has feet fitted.
No original box but unit will be suitably packed
Any questions please ask.
