onix oa21s question

[Conan]

Just bought a Onix OA21S.
Great sound. I prefer it to the Nait2.
Thing is that the left chanel on my Onix sounds lower than the right chanel no matter which input I select.
Can anybody help me solving this?

Come on guys.this amplifier is a gem and I would like to restore it to its glory.
Any recommendations of were I could send it to be fixed?

Did you try swapping speakers around to rule them out? If not that, amp probably needs a service - it could just be resetting bias, but most likely it would benefit from having a few caps changed too - where are you based?

It's the amp , I'm sure the speakers used are Usher S520. I'm based in Birmingham UK
