Thank you Fernseh, I am glad that I have inspired you to play with your TT1 too. Unfortunately, as luck would (wouldn't) have it, I only have one volume of Newnes and that is for 1959/60.

You wrote - ' the time base is free running'. Forgive my perhaps apparent ignorance but what is that statement telling me? Is is a statement of fact i.e the time base is of a type that free runs because that's how it is or it is free running but it shouldn't be. I am sure that you're being helpful but am I to presume that it IS a fault and if so what would be some clues as to the reason. I will check the time base circuit for 'duff' resisitors but with little knowledge of transistor technology and no circult diagram I shall be free running without a safety net....so to speak.

Many thanks
