Massive p3000.1

The amp with the power terminals is the output inductor that is getting hot.

How do the two drive signals coming out of each driver board compare.

One driver board is oscillating at a much lower frequency. Does the frequency remain constant when you drive a load?

When the driver starts to heat up, can you feel that one particular area is heating up quicker than the rest?

Would that be before the gate resistors?

I'm referring to the signal on the output terminals of the driver board.

I will have to trace them back. I don't have a schematic for this board.

The pins should be similar to the SLA1500 with a slight difference in layout.

Hi perry been a little busy would you like me to check the gl1/gh1 or would you like mosl1/mosh1.

 

[Perry Babin]

Check all.

So I probed around on the gates and found that it was the signal from the driver board. I heated up the epoxy top and cut around the edges and u702 was unsoldered. So now the amp idles at a nice 2.4 amps and torroids are cool.
