It's nice, good slam. Surprising because it is a Philips. Class H, so it has two voltage rails for different power demands. Very strange parts inside, though. Lots of their own transitors, etc, as usual with Philips. Can be difficult to repair properly, if needed.
I love the feeling of the volume knob and source selector. Nice light bulbs to indicate source, too. Those are 12V 100mA 5mm diam if some are blown. Very easy to find.
Biggest negative is the plastic face plate. Hideous and feels terrible to the touch.
