Hi there
I own this baby since many, many years. I think my Nait2 is about 20 years old. I never had any problems with it but now the phono stage is out of balance. All other input stages as well as the power amp section are working perfectly balanced (meaning left and right channel a balanced). It seems to me that one phono channel is working at normal output level whereas the other one has significantly lower output level and sounds thinner than the other phono channel. It's definitely not my turntable that is providing an unbalanced signal between left and right channel (I've switched the channels in order to exclude the turntable as root cause.
Since the rest of the Nait amplfier sections are working properly the issue must be located within the phono pre-amp section.
I know from tube amps that electrolytic caps dry out and need to be replaced after 15 to 20 years. Could it be the case that the electrolytic capacitors in the phono section have been dried out (these axial 47uF/25V)?
I've got a picture on phono pre amp section here:

Any advice out there?
cheers
