I purchased this McIntosh C-28 pre-amp in 1976 along with a
MC 2105 amp, which is also for sale. I recently had this serviced at a certified McIntosh shop and it was cleaned and had new bulbs installed and I will supply a copy of the invoice if requested by the buyer. I also have the original owner’s manuals. It has a nice walnut case, and I have worked to maintain this pre-amp over the years, as it has been quite a reliable and enjoyable unit to own. As mentioned above, I also have a companion McIntosh MC 2105 amp to sell and will discount the purchase price of each by 5% if purchased together.
