Naim 32.5 one channel not working on stereo setting

Hi,

One channel is out with the stereo/mono channel set to "stereo", but fine on "mono". Moving switch back and forth a lot doesn't do anything. Any thoughts? Thanks -

its not the output(321) or the relay (325) boards .turn the balance pot fully about 50 times . if it does it on line level input make a note of the channel down and then swap over the 324 input buffer boards as opposed to the tape out put boards,if still the same channel down then its probably one of the toggle switches,
