テキスト:

You should unsolder the suspect output transistors to trace the circuit backwards for a possible short. When you plug in a speaker, you are adding a shunt circuit to mask an internal short. So if you only plug in one speaker in any channel, then the amp will stay on, OR ONLY CH 1? Testing components in circuit is a preliminary test, not a final nor reliable test. Since you have a stereo amp, that is a left and a right that should be the exact same parts for left and right, without a proper oscilloscope to diagnose, you can swap parts around until you find the actual problem, easy enough, yes.
