Amplifier problems: Can only hear right channel

by Erik_Twice Fri May 06, 2016 10:34 am

I finally got the cables for my dad's amplifier and it seems to work well, except that I can only hear one channel when I plug in my headphones.

EDIT: I've tested a bit and it seems the signal simply doesn't reach the left side of the amplifier. The actual connections are good and if I plug a couple of headphones that cause interference, the left needle moves like the right one.

The left needle doesn't move when I first power up the amp so this must be a very easy fix. I opened the case and everything seems to be in top shape, it must be a bad conneciton or something like that.

Thoughts?

I'm not technically minded, but it sounds like an issue with the headphone jack. Have you cleaned that up? Are your headphones with or without a mic option? I think that might bring another issue.

Ok, I think I might have found something's up: When I first turn on the amplifier, the right speaker indicator goes full to the side and then comes back. But the left one stays still. Perhaps it is not working?

Is the headphone jack mono only?

No, it's stereo. I thought so at first but no, it seems there's no signal in the whole left side of the stereo. But when I open it, everything seems fine.

There must be a problem somewhere and it must be a really easy fix, but I have no idea on how to do it! :lol:
