As far as I know ( and I am no expert , but know the basics ) ......an ‘importer of goods’ MUST ( by law ) carry ‘X’ amount of common back up parts for a product they are selling and offer a service / repair procedure that guarantees the consumer a speedy resolution to any warranty issues.
As Nino stated , the home pinball buyer ( is surely ) now Stern distributors biggest market here and they surely must adapt and change QUICKLY if they are selling predominantly into that market.
I honestly think if properly ‘challenged’ through the appropriate dept on a warranty issue that currently the pinball consumer would win out as things currently stand
