To connect your original UK Phillips radio – or any Philips radio with the same input/ output sockets of that era – to a CD Changer you will need one of these adapters. Plenty of them usually found on

If the Phillips radio you are using has a CD labelled button (like the original 741 type) then the radio will only accept a CD Changer. If it has a SOURCE (SRC) or AUX button then it may take a CD Changer or bluetooth adapter.
