Idea's --- erm , Power Op-Amp-- There used to be some in this package. Power regulator of some sort. Motor driver. Stepper motor driver even ? Perhaps a dedicated TV frame output stage. T.V. -- S.M.P.S.U. I Dunno :) It "looks" old. Has that 1980's ish look.
You've no idea what it was in ? |

| i don't read japanese, but i can read graphs ok.... 0.75W or so before clipping into 8 ohms. at 1% distortion, it looks like an output amp for a table radio or a tv set. actually the data sheet sets really loose specs of 0.5W at 10%THD |

Maybe I'll make a headphone amp with it, as a benchmark for "high distortion"....so I know what to listen for...:D
