TPA-1 Replacement motor? 24mm diameter with 2MM shaft should be perfect with the right torque curve 1/2 the rpm of some others

Just got done replacing C1, .mp3 player sounds pretty decent! Might keep it on for a while, hope it doesn't need heat sinks on those big 'ol outputs?? Time for the infra-red gun . . maybe better tone with the cabinet closed up . . .
