Up for offers is a Yamaha power amplifier MX-600. The condition is very good, I would give it a 8.5 out of 10. The face plate is all most perfect with novisable scratches. The amplifier functions as it should with equal power out of each channel. If you are looking at this amp you already know the specs but for those that don't know its rated at 135 rms @ 8 ohms, 230 rms @ 4 ohms. It does have a voltage selector in the back plate. This amp looks much better in person than the pictures show. From a distance this amp looks great! This is a heavy (28 lbs) amp so the shipping will be a little expensive.You will not bedisappointed with thisbeauty.Any question please ask, good luck offerding.
