Pioneer Stereo amplifier SA-7800 sound problem

Good afternoon Gentlemen,
I have a Stereo amplifier SA-7800.
The problem that I have is when I listen to the music
I set the mode selector to the stereo mode or all other mode, the sound of the column left side is louder than the right side.

I change the connection of the speaker wire (right to left and left to right) in the rear of the amplifier and the problem is switching to the left side I mean the right side is playing louder thant the left side.

Do you know a good and honnest repair place in Montreal or Montreal area that I can rely to repair my stereo sound system?

As you seen by the model of my stereo amplifier it's not and recent one but it's one of the most reliable sytsmtem that Pioneer manufacture on the market my other components are Stereo tuner TX7800 and 2 speakers
HPM-100. I own it since since 1978.

Thanks Gentlemen for your help and quick response.
