Ok, time for an update,
Firmly believing that trying the simplest method first is the best policy I tried tapping the cassette, no good. Then pressed the small button below the eject button, unit clicked twice then fell silent, tried pressing the eject button, no good. Had a few attempts at this with no joy. Resorted to tapping unit one last time as it sounded like it was trying to work, this time I tapped a bit harder, frustration setting in, and hey presto, unit ejected when button pressed
. Have re-inserted casstte and cycled thro CD's, all is well and playing fine.
Many thanks to all who replied, most appreciated.
Will be posting another small issue soon, still have to replace crank pulley on 'the race' when time and cash permits.
Cheers
Stuart
