For your consideration, we have a superb, fully serviced Rotel RB-1080 Power Amplifier. This amp came to us in a trade with one channel not working. We went through and diagnosed the amp, and replaced faulty transistors, and some caps on both amp boards. The amp was biased, and put through its paces on our bench. We followed that up with a week in our house system where it performed flawlessly.
The amp has ample power at 200 watts per channel into 8 ohms, and has both balanced and unbalanced inputs.
Physically the unit is in very good condition, with some small blemishes and scratches. The front panel is in very good shape, with one small ding on the heat sink that is second from the right. Overall the unit presents itself very well.
We don't have the original box for this unit, but we take packaging and shipping seriously. We spare no expense and use heavy duty boxes, several inches of polyethylene foam on all sides of the unit, and use water activated, fiber reinforced tape on all seams.
The RB-1080 rests close to the pinnacle of Rotel’s two channel power amplifier offerings. Power output (200 watts per channel into 8 ohms) is extraordinary. The Rotel-made toroidal transformer feeds separate power supplies for each channel.
British BHC Slit Foil storage capacitors provide quick charge/discharge times for instantaneous response to the most demanding signal peaks. Damping factor, at 1,000, shows this amplifier’s unparalleled ability to lock onto the most difficult speakers to precisely control diaphragm motion and give you superior sound quality. Heavy duty dual binding posts encourage the use of the most advanced speaker cables while switchable balanced (XLR) and unbalanced (RCA) inputs provide extraordinary system configuration flexibility. Front panel heat sinks add a strikingly dramatic look. Separate inputs and outputs for 12 volt “trigger” signals and a detachable AC cord make this amplifier well suited for custom-installed systems with total remote control capability.
