Default Quad 33 one channel brighter

Hi Folks, Looking for some help on this, this was my old set up and a friend bought it from me a few months ago.
He complains that one side is brighter sounding than the other. I have had a listen and it is brighter on one channel but only on phono input. I assume the "dull" channel is the faulty one.
The difference on my speakers isn't huge but he says it is much worse on his speakers.
I swapped the tone boards over but didn't make any difference. I have checked everything on the phono stage board and can't find anything amiss.
I should mention that all the electrolytics were changed a few months back and I have been over them in case I had fitted an incorrect value somewhere.
There is very little left and I am at a loss as to where to go next. Any suggestions gratefully received. Norman
