I have a generation 1 Sonos system and really don’t want to upgrade. However, I am experiencing issues 0laying from my turntable through the Sonos connect - agree a couple of minutes it cuts out. Have tried everything recommended  and have decided the connect probably has a fault and I need to replace. Obviously not made now but can anyone suggest a place to buy a replacement which is in working order and ideally with some form of guarantee? Plenty on eBay but generally private sellers.
