Hey.
I bought this non functioning amp off of another user on here.
I am trying to figure out what is wrong with it.
I have gone through and used a DMM to check the resistance between the pins of the mosfets, however, I do not know if i am doing it correctly.
Here is an illustration:
Now, I tested all the mosfets, on both sides of the amp, and they all had similar readings. I went around, and tested all the resistors and again, they all had very similar readings.
On the other half of the board, I tested the larger mosfets as well. I had two test between the two outside pins to get a reading, and on the few that i could reach, the reading was 9.5 on the 200k setting. Since I wasn't able to reach them all, I tried the first prong on the first one, and the last one on the last mosfet, and I still, had a combined reading of 9.5... which to me seems like they are all fine.
There are two other devices, look like mosfets to me, but are not grouped together with either other set.
They however, also, show resistance, between all prongs.
I have looked over the board, and do not really see any puff caps or burn marks. I haven't taken the board out of the case, because quite frankly I haven't been able to figure that much out yet... So, anyone have some tips for me?
