Mono has one channel. Stereo has two channels that are different.
A mono amp can drive two speakers but then both will play exactly the same thing and will be mono.

I forgot.
There were some "stereo synthesizer" circuits a long time ago.
They made the bass "boom, boom" in one channel and the high frequency "tweet, tweet" in the other channel. It did not sound anything like stereo.

True story: early rock and roll was often recorded in mono. The Rolling Stones best album ever (High Tides and Green Grass) was a mono master. They re-released it later converted to "stereo" and it was absolutely awful. If you wear headphones, you can hear them dialing it apart on the first track and hear the image separating. Truly awful sound. No sense of stereo at all.

FYI, High Tides and Green Grass was 1966 and Through the Past darkly was 1969. I would have hoped they would have gone to stereo masters (and decent sound quality) by 1969. I do have both albums in vinyl and I recall the newer one sounds very much better than the old one.

Simply make another identicle mono amp,one for left and one for right channels.you can control the volume with a twin gang pot.What are you using for the input?

Sounds like a mess mate, hed be better off building a separate stereo amp, throwing it all on one board with a selector switch to have one or the other.

My wife is my mate. I am not your mate.
Guys who are in the Navy or who work on a ship are mates.
Some guys have another guy as their wife (mate).

We have a different understanding of that word then. Its merely a figure of speech to address someone in a friendly way round here. And before you say it, I know, you arent from round here. Obviously.
