power supply issues memphise 1000d

jf8620 · 10th May 2006, 09:25 PM

I fixed the amp and then it broke with a day again. Can't find the anwser this time i belive my subs are shot and that was the orignal problem.

Now my issue is the amp is drawing too much power. when it turns on it clicks and flashes the green power led rapidly. Then it blows a 10amp curent limter in the B+ line.

I think it has to do with the chip that the driver's are on becasue the traces where bad so i had to add some wires to connect them. Any know if u can buy just the chip? think its call an smtp

Did you replace the driver transistors?

Are you sure that you have the jumpers routed properly?

Is the driver board in a socket or is it soldered to the main board?

Can you post some good quality images of the repaired areas?
