I Have a KN7000 keyboard and at this moment I am having trouble with the tempo wheel adjustment Knob, when you turn it to adjust the tempo it does not work unless you push it hard and even then its a job to get it to adjust the tempo, any suggestions as to what can be done? thanks Raymond.
Oh dear, that doesn't sound very good does it? As I often say, I'm not an engineer, I think you have to take this to someone to fix it. Many components are still available from W D Greenhill I understand and it sounds as though you need a new tempo dial.
Hope an engineer might join in this thread who has encountered a similar problem before and fixed it!
