This unit was built in Montrose, MN in 2008 and has lived in a home studio ever since. It will produce at least 1000W bridged at 8 ohms and 1250W output bridged mono at 4 ohms (the label also mentions 1440W total output), or 500 ohms per each channel at 4 ohms. It can drop to impedances of 2 ohms on each channel (625W/ch). It is in great cosmetic condition with only a few small scratches, as shown. Function is perfect. My favorite feature is the tone-balance control for each channel, which allows a quick shift toward highs or lows to compensate for room dynamics. Very handy indeed. 2 rack spaces, weighs 28 lbs. I am asking $550 shipped within CONUS. Manual is here: http://eden-electronics.com/info/manuals/pdf/WT-1550 and 1250 manual08012005.pdf I will also be selling two Navigator preamps and several 410 cabinets in the very near future, so keep your eyes peeled, Eden fans. Sorry for the blurry large-scale photos. I have several sharper close-ups that I will post as soon as I am allowed. Also happy to e-mail additional pix.
