The McIntosh C11 is a vintage 2-channel vacuum tube preamplifier produced between 1961 and 1963. It is recognized for its all-tube design, utilizing a selection of high-quality Telefunken ribbed plate 12AX7 tubes for optimal audio performance. The preamp underwent a full electrical restoration which included a rebuild of the power supply and replacement of out-of-spec coupling capacitors, ensuring its operational integrity. This model features a classic aesthetic with an aluminum front panel and glass faceplate, maintaining a physical condition that reflects careful ownership over the years. It is equipped with multiple inputs, tone controls, and a loudness function. The unit typically exhibits slight imbalances in volume controls which can be compensated to achieve a balanced audio output. The recommended cables for connecting this preamp include various options from Kimber Kable, particularly for RCA interconnects and phono applications. Despite being a vintage unit, it maintains a working condition rated at 10 out of 10, reflecting its reliability and performance after restoration.
