Excellent sounding and powerful amplifier Have tested the amps performance with both Klipsch 600M and Emotiva T2+ speakers and they sounded great. Even better to watch the full green meters in action! The amp if in perfect working condition. The left wood side piece has a piece of the wood veneer chipped off as shown in pictures and the B speaker button is chipped in the left corner of the button. Have tried to find a replacement and thin the best option might be to 3D print a replacement. Other than that is in good condition on the exterior. Green lights show much better in person from LED upgrade than the pictures do it justice.

Onkyo IntegraM-504 Power Amplifier You are bidding on a massive Onkyo Integra M-504 power amplifier. This audiophile grade amplifier is rated at 165 watts per channel at an amazingly low .003% THD (total harmonic distortion). This amp powers up and immediately blows a 6 amp fuse (see the pics for the location of the fuse). It remains powered up, but does not provide any output. Both meters have been checked and are functional as they should be. Cosmetics are nice with only a few minor blemishes making this an excellent project box. Please note this amp weighs just over 55 pounds so be ready to use some muscle getting it on the bench! Please note the Coke can in the pictures is shown only to illustrate the size of this beast (it is not included). Good luck bidding!
