Hi,
I had a problem with one of my amps. How it failed it was because I was positioning it in my trunk the wires were not insulated where they were connected together the B+ was covered aswell as the GND wire, anyways two of the speaker wire and the REM wire was not covered and I was moving the amp around the positive rem wire touched one of the speaker connections and the amp I believe got damaged. Btw it is a Rockford Fosgate Punch 150 very early version. Amp turns on but the output won't play anymore it just makes a click pulse sound through the speakers and that's it. It did smell like something fried inside. And when I checked I saw that the legs of transistors marked 2N6487 M325k, those are the ones were the legs turned gold usually they are silver. Is it possible just those are bad and not the 2N6491's? The real question was: can I use STMicro and ON Semi together? I found those exact parts that are available to purchase. This is a really good amp and i got to admit I am an dumb a** for the mistake i did. So if anyone can give their input as to what i can do to make it play again.
Note: I am limited to electronic testing equipment to use so please bare with me. However I do have access to vom, solder iron, ohm meter and that's about it. Thanks alot. If you also need a picture I can post one....
