Hello Roger,
I purchased my AR-100 in 1998, not long after it was first available.
Replacement panels were supplied for me free of charge in June 2005,
but I believe that some folks had to pay.
The gold lettering remains in absolutely perfect condition.
Good luck with yours. I presume that your machine either had new
panels at some stage, or was not one from the faulty batch.
Cheers,
