Here we have a used Mcintosh C27 Preamp for sale. It has just been serviced and many electrolytic capacitors have been changed for top quality Nichicon audio grade and Wima film capacitors. All the transistors in the main amplifier section have been replaced with ultra low noise and high performance parts. The controls have all been cleaned and lubed. The Aux and Tuner inputs all used redundant coupling caps in Mcintosh's original configuration but this has been improved upon here. The Tuner input has been modified to remove these redundant capacitors. The Aux 2 input has brand new Nichicon muse capacitors and Aux 1 has the original capacitors which gives you three different sonic qualities as your disposal.This unit has been tested on the Panasonic VP-7722a audio analyzer and meets or exceeds all published specifications. The unit is in good overall condition with some corrosion noticed on the pan locs, RCA jacks, and the sides of the case from its life in Japan. The front glass is in overall good condition with some minor imperfections and the front panel illumination is working.
