For sale is a Vintage Mcintosh C27 Preampkifier. It is fully fuctional and has been thoroughly tested. Excellent waveforms and riaa curves in the phono stage. See pictures for physical condition. It is original and has been thoroughly tech bench tested. As with any vintage Mcintosh stereo equipment regular service and maintenance will be required should any irregularities or problems arise. In my opinion it is one of the best bang for the buck vintage preamps.
