McIntosh MC501 mono amps (pair)

McIntosh mc501 Monoblock Power Amplifiers (pair). I purchased these from a dealer in the Bay area who took them in on trade. They are in very good condition- operationally perfect and minor flaws in appearance (There are light scratches on the chrome underneath the up facing connectors in the rear of the amp probably from making connections, These cannot be seen from the front of the amp and I can't photo them because of reflectivity of the chrome. There is a slight roughness on the front top edge of the gold trim piece on one of the amps, again not noticeable from any distance. The same amp has a 1/2" long scratch in the top of the glass section. The scratch is light in color and again not noticeable from any distance. This could be fixed with a Sharpie if it bothered you. These are the only flaws in the appearance and I consider them minor. I really hadn't noticed until preparing this ad.)

These amps are very heavy (91 lbs each, 106 lbs packed for shipping). I have the original boxes and manual. No power cords, but you'll want to use a good aftermarket cord anyway. The shipping calculator is for one amp only, so double the estimate. Local pickup is available. I am located in Fresno, CA and would be willing to meet half way to LA or SF areas. Paypal fees are 3%.
