About this model

The MA6100 is a solid-state McIntosh integrated amplifier, made from 1972 to 1979 according to the company's legacy list, and rated at 70 watts per channel. It belongs to the period when McIntosh's look settled into its familiar form: black glass front panel, illuminated lettering and, from around 1974, blue meters.

This example, serial AE8331, was described as all original and working, with clean glass and some pitting and oxidation on the chassis. The seller's remark that it sounds "almost tube like" is a common way owners describe McIntosh solid-state amplifiers of this era.
