Amplifier makes high pitch noise

[idan167]

Hello,
So accidentally I ruined my amplifier and i replaced it with other one i had, and once i did i started to hear high pitch noise from the speakers that connected to it. very annoying..
I thought it might be from the rca but i disconnected them and the noise was still there..
the amplifier is ds18 candy-x4b, i once accidently connected the positive to the negative on this amplifier and never used it after that till today.
do you think it's because of that? on the old amplifier i didn't hear such a noise..

Its a possibility. You might want to look for a new amp.

yeah i already started looking for one, but didn't want to spend more money before knowing the real reason behind that.. i guess the only way to know is to buy a new one and connect it to see if any difference.

Can you take your amp to a local shop to be tested?

Unfortunately barly someone does these things in my country, and the ones that do, makes it so expensive to test it or even fix it that testing it doesn't worth it..
