McIntosh MC-225 Stereo Tube Amplifier Circuit Study - Signal Path Illustration

I explain the signal path and phase inversion circuit of the McIntosh MC-225 amplifier. One of my favorite amplifiers next to my Fisher and Marantz amplifiers. This is likely very similar to the MC-275 and MC-240 circuits as well.

I have a MC225 completely restored and like it very much. I find this very informative.

Thanks for posting basic push-pull signal flow through a 225.
