Question about MB Quart RAA1000 Car Audio Amplifier
Hi, I have a MBQuart RAA1000 mono amp, It powers on, but stays in protect mode. I have checked all the wiring and everything is fine. I have tried for almost 2 years to find a solution to this problem and cant seem to find a cause for this, or anyone that will fix an amp. If anyone has any idea what could cause this, please let me know. Also I feel I am a very technical person and would be comfortable fixing the amp myself if someone could point me in the right direction to get started. Thanks
Shorted output transistors are the most common reason for amplifiers to go into protect. How much do you know about electronics/electronic components?
If you're a newbie, read THIS page.
Would it be possible to send me a set of high quality photos of the amp's internals?

In that group of transistors, measure the resistance from the center leg to the outer legs on each of the individual transistors. If you find any that read near 0 ohms, you need to remove them from the board and test them again. If they still read near 0 ohms, they're defective.
The SSP45N20B are difficult to find. The SSS45N20B should be a good substitute.
