McIntosh C11 – Used in excellent condition (please look photos). 100% all functions operate , it works at 110v. Six new balanced tubes JJ 12AX7S are installed, anyway I suggest to find 6 vintage tubes. The 4 central knobs have been replaced with four original McIntosh knobs that are a little bit more bigger.
About this model
Despite the title, the C11 is a preamplifier, not a power amplifier: McIntosh lists it as a two-channel vacuum tube preamp made from 1961 to 1963, between the C20 and the C22. This example worked at 110 volts and had six new JJ 12AX7S tubes fitted; the seller suggested finding six vintage tubes instead. Four of the central knobs had been replaced with slightly larger original McIntosh knobs.
A short production run makes the C11 less common than the C20 and C22.
