The Magnatone M-10A is a mid-1960s revision of the M-10, a two-channel combo from Magnatone's M-series. Each channel has high- and low-gain inputs on a 12AX7A/7025, its own Bass, Treble and Volume and a Bright/Mellow Tone Boost switch. A 12AU7 varistor bridge driven by a 12DW7 oscillator gives Magnatone's pitch vibrato, a 12AU7 and 12AX7A run the delay-line reverb, and a 12AU7 inverter drives two 7189As.
