There's a BAX outlet in the UK.
I bought a new amp from them ( not B stock ) and it arrived with a faulty EQ, and so was sent back. After printing the return label they sent, i noticed it was going back to the Netherlands, so i guess repairs are done there.
Trouble was, it came back with a note saying " amp tested fine, no fault found " but it had the exact same fault. I did the return, again, and got my CC company to do a charge back, just in case
