Punch 250a2 problem

[Whosnxt]

This is not same amp as other thread. Ok i replaced 2 output transistors both ps fets with 3205's and 47ohm res. On gates also replaced all drivers just because i have like a hundred of them dont know if they were bad. The amp works perfect only problem is when i turn remote power off the power led stays on, but it disables amp like it should?

How long does it stay on?

Do you have to disconnect the battery wires to get it to go out?

 

[Whosnxt]

Never goes out it stayed on all night. And yes i have to disconnect all power for it to go out.

Did you do anything with Q3 when you were replacing parts?

 

[Whosnxt]

Yes i replaced it with new one

 

[Perry Babin]

Are you sure that you used the correct part?

Are you sure that you have it soldered to the pads properly?

I put a 3906 on it. I checked 2 legs they have continuity to next spot on trace but cant see trace on 1 leg. I will resolder it and see if that fixes problem

Thank you very much Perry your a smart guy i tried resoldering that didnt work so i soldered another one on and that fixed it thanks i think i got original too hot cause when unsoldering it a leg fell off.
