Thanks all, it's taken me a while to work out how to find my OP, a bit slow I am
. I'll have a go at opening it up (the player), it is a relic from my wife's Mum's home, amongst other things such as a Bush VCR of no use now. I hate to see things being thrown away, I've just fixed an old Wharfdale flat screen, caps in the PSU, and have lined up a couple of Ghetto Blasters (is that allowed?) Bush & Panasonic, and more advanced an RA17 radio and a Studer-Revox G36 tape player.
Cheers and thanks again.
