Help on my favorit amp

Hi, i'm new here and i'm french then sorry for the mistakes !

I have a problem with my Aura VA100 mkII amp.

There is a shift of level between left and right chanels. I will try to discribe the problem ...

At zero volume, i ear sound on the right chanel (at low level), nothing on the left (this one is working good). When i turn the volume, the right level decrease to zero and increase normally after but never reach the same level as the left !

What is wrong there ?

i guess it is the ALPS 50KAx2 Stereo Log Potentiometer,
but as i'm not an expert then i ask before :-))

If not what could be the problem ?

Yep sounds like a pot that reached the end of its road.

It is easy to compare how the 2 channels track in terms of resistance, useing a multimeter...

Thanks to reply so fast !

I hope it's the pot (easier LOL), but i don't really understand how this can happen to a pot !?

Is someone already saw that ?
