    Panel is done. The alternator is here. Got me some time off, can't dismantle it in the dark.
    And to fill the time an urgent job came. Something I fixed couple of months ago.

    A Hi-Fi Entertainment. A Japanese made, an Original Sony. It got ruined because the owner thought it was a football :eek:.
    Please, do not ask what happened, it's not not my problem.

    I fixed it from top to bottom. The Tuner, DSP and Amplifier.

    In the Amp I replaced some blown caps together with a STK. The Sanyo Hybrid Power amps.

    I bought the STK from the local store, actually the owner bought it and I soldered it. I did say "I wonder how long it would last.?

    Answer is here. I bought another from them and installed it.

    To waste my time I went down and dirty in to the STK....see the pic :D

    I thought of doing some R&D my self.

    Checked them power transistors and they show confusing values. So I got rid of em.....

    I was thinking, would it work if I use discrete output stage in it.

    Time to find out......
