Hang on to it, but as far as the C32 is concerned, DO NOT ALLOW ANYONE TO EVEN OPEN THE COVER IF IT WORKS FINE.
Explanation: The C32 was McIntosh's first and only product to incorporate the then new Ribbon Cable technology, and the mfr of said cables was new and inexperienced: a ribbon cable (formally known in electronics as a FFC (flat flexible cable) is a flat ribbon of conductor laminated between two layers of plastic to form a wide paper thin cable with either pins or tinned conductors at either end).
GUARANTEED, the ribbon cables inside the C32 will be delaminating from heat and poor manufacture and once removed for service will split wide open like a ripe banana and be IMPOSSIBLE TO REINSTALL.
McIntosh NO LONGER CARRIES THESE proprietary cables nor are they available anywhere else(the new stuff is far finer/thinner and has more conductors, etc). I oughtta know: my first Mc was a C32 I bartered a computer repair for and spent over 400 hours hand making new cables for it so I could sell it on eBay. NEver again would I touch a C32.
McIntosh Service Authorized since 2005, so I speak with some background.
