Hi I'm new here, I'm from Italy 🙂, sorry for my bad english.
I have a PG MS-275, unfortunately it have distorted output sound from the two channel.
Two of the four red led are lightly on and the other two are working fine.
I change the caps and check all the transistor but I can't find any problem, also my external power supply is good.
I try also with another pair of woofer but the problem is still there.
The distorted sound occurs more when the music have bass so I think it's something relate with power but I don't know what it can be.
You have any advice?
Thank you!😀

I've seen the LEDs fail but it's more common for one of the flameproof resistors to be open or out of tolerance if you cannot find the problem.
