Up for Sale is a McIntosh MC-502 Power Amplifier. Other than the cracked faceplate which occurred during shipping, the unit is in very good operational and cosmetic condition. It is being offered for sale at a reduced price due to the cracked faceplate. The unit was serviced and brought up to specifications in January of 2015 by Classic Audio. This Model is 50wpc (8ohm) and is switchable to a 150wpc mono. With the front panel line level inputs, it makes for an excellent quality CD or Headphone amplifier. If hidden away as a center channel amplifier, the faceplate would not be of importance. If the appearance is important, it would cost about $200 to have the faceplate replaced. FREE SHIPPING to USA This is a good opportunity for a first time McIntosh owner or as a repair project for the veteran. This amplifier is in working condition, only issue is the cracked faceplate. NO RETURNS. The unit will be shipped in the returned Fedex double boxed carton. PayPal only. Thanks for looking!
