Tested and fully working Cleaned internally of dust and fan cleaned Good condition, some small marks, see photos This amplifier has 4 channels that can output 50w @ 4ohms each or 50w at 100/70v It also has the ability to be used with an Rl-1 or RSl-6 to control the volume level and source input remotely. High quality fan so pretty quiet. A front plate can be purchased separately to restrict access to eq controls. Most Phoenix connectors are included. You will only require some to use the remote volume plates.
