McIntosh A-116 Amplifier Mono Block Amp First although listed as for parts, it has been in storage for years, and was originally ordered to be used in a Herman Miller ESU storage unit. It was probably used very little, and we have only listed it as for parts for Ebay return reasons, but it is probably in original working condition. It is a 30 watt mono amplifier intended for use with McIntoshs C-8, C-4, C104, or C-108 preamplifiers and was accordingly fitted with an octal socket which supplied power to these units. It could, however be used with other independently powered control units. (Today many people buy two and make them into wonderful stereo systems.) The original A-116 was replaced by the A-116B in 1954 which was more commonly known as the MC-30. Frequency response was 20-30kHz (±0.1dB) and distortion quite low at 0.5%. Two 6BG6/1614 output tubes gave 30 watts continuous power. In 1955 is sold for 143 dollars!
