Hello everyone, I have a used vintage Ariston Maxim Amplifier - not working as the main( mother board) has packed up. Can anyone guide or advise me from where I would be I would be able to get a new or old (used) one. As tried contacting Ariston in Scotland and getting no response due company shut shop.
