I remember taking in an LP12 with Akito for a service and Cirkus addition.
The L on the tonearm plug looked like it had been mauled on the Serengeti!
On quizzing the customer he had taken it to a well known dealer that had dragged their feet on the job, but he claimed he had never "been in" himself.
It really looked like someone had very forcibly used pliers to yank the plug out without removing the grub screw first.
The deck was beyond out of tune, it was miles out in every way and sounded horrendous. Bad member of staff at dealer or naff DIY, I will never know.
