Power amp is an ATI AT2505 5 channel home theater amp in like new condition physically and functionally. It sat in its original box for the last 7 years. Box, manual and power cord included. The amp will put out 500 wpc at times and needs a dedicated 20 amp breaker to do so. 250@8ohm. No markes on it, period. Perfect shape. Literally. Led power light flickers, bulb will need replaced or resoldered. Local pickup and demo in Bremerton 98312. The amp weighs 106lb. Not the heaviest amp ive owned by any stretch of the imagination. I had a 2 channel Krell that was 185lb. Having owned as many pieces of audio equiptment as i have, ive been around a while. I know when buing on FB and other places we look at listings and think...is this guy serious? "Like new" right! Uh huh. Well, get to know me and my insane audio journey before you scoff too much. Its all legit, and my rep in audio can be verified. Google my middle name and click images. Thats my user name, and there you should at least learn ive owned enough that maybe, just maybe this aint no Goodwill special. Take care,
