SA-3 stereo amplifier right channel not facilitating stereo
I have a Bose 251 environmental speakers attached to a Bose Lifestyle SA-3 amplifier, which in turn is connected to a Bose Homewide wireless Audio Link. The speakers were replacement speakers purchased on December 9, 2011, while the amplifier and Audio Link were purchased in April 2008.
On New Year’s Day when attempting to play music there was no output through the 251 speakers. I replaced the 12 year old wires with new 16 gauge wires and sound emerge again from the speakers. However, while the speaker that’s attached to the left channel was playing normal, the one attached to the right channel was almost inaudible. I switched around the speakers to see if the speaker attached to the right channel was the problem. However, both speakers when attached to the left channel works properly, but which ever one is hooked up to the right channel plays very softly.
I subsequently changed the amplifier mode switch from the factory set ‘stereo’ to ‘mono.’ When this was done both speakers playing evenly on both channels. Therefore, it seems that the problem only exist a on the right channel when the amplifier mode switch is set on ‘stereo.’ Is there a ‘cure’ for this?
