Car Audio Alpine MSP M1000 Amp

[Deazy]

I have been running an Alpine Msp M1000 amp in my car for some time now. Just recently it gave up on me, It was turning on and receiving power but would not output power. I opened it up and found a broken transistor, the only problem is in removing it i broke the plastic and now have no idea of the rating of it. If someone with the same amp could help me out and let me know what the rating is i would greatly appreciate it. I also already called Alpine and they basically told me they had no idea of the internals and would have to pay 100+ to have it fixed.

so how about a hint, got a foto or any markings on the board near it?

Sorry I was in the process of uploading it, the transistor in question is exactly the same kind but had a different rating.

How about the pictures of the whole board? There should be another set of transistors with the same set up, but cannot tell until we can see the pictures to see what the function of that circuit is for.

i cant see any pictures.

here are pictures of the full board and a repost of the transistor location

OK , those three Transistors seem to be setup for linear Voltage regulator circuits, exact regulated Voltage are, I do not know.
But since they are for regulator circuit, then we just need to find out if it is NPN or PNP transistor, that will require some circuit board tracing.
