I have a 1978 Kenwood KD-2055 ceramic base turntable and have an issue with the tone arm not tracking all the way to the end of a record. It gets near the end of the last song and starts skipping and will not go far enough for the auto return to operate. I can pull the cue lever up and swing the arm over to that position to where it stops and there is an obvious place that i have to push a little harder to overcome the sticky place and it will then return on its own. Is there an adjustment somewhere or does anyone know why this is happening?
