The M6 was a two channel combo amplifier with the two varistor vibrato and a 12" Oxford speaker. there are two input channels, each with high and low gain input jacks. Each channel has a dedicated "Loudness" control and share a single "tone" control along with a three position "contour" switch. The preamp uses a 7025 tube and one section of another 7025. Vibrato has speed and depth controls and a foot switch jack.


Special thanks to George Nichols for these pictures.


The speaker is an 8ohm Oxford 12" AlNiCo (probably 8 ounce). The output transformer does not have ultra-linear taps like other 7189 Magnatone amps (M7, M10, etc).

The M6 was produced for a short time and was dropped from the catalog by 1965, perhaps due to the feature and speaker similarities it shares with the M8.
