Thank you Craig. That certainly was the right direction to point me in!
2 days ago I thought this lovely old B & O may never work again. I took it up for Tim to have a look at yesterday and now it is working!! I am so pleased. I'm now going to unearth the old B & O speakers and turntable to complete the system to as it was, when my Dad bought it back in the 60s. I can't wait. I hope the turntable still spins.....
