Thank you for your quick reply Martin. I will go and attack these clutch units straight after breakfast and let you know how I get on. Jim

Thank you for your reply peter and yes the BM1700 is very similar to the 1600. At least it shows the bits I am interested in, ie the clutch units, have not checked the circuit yet.

Thank you for all the advice but what I really need is to know how to take the tractor units apart and replace the rubber washers. The previous owner of this appears to have given it a good spraying with something like WD40 which I dont think did it a lot of good.The tractor belts are turning the shaft that drives the clutch mechanism. Do the sliders

I have a problem with the sliders that control bass treble and balance. They dont move when asked to do so by pressing the relevant control. I am not sure how these sliders work? The volume slider seems to be engaged all the time. Is this correct? Does anyone have a copy of the service manual for this unit.There would appear to be two 1600 tuner amps

Hi Martin, I am looking for just one pair. Original used would be fine or factory new. Yes I am aware that there are counterfeit ones about. Jim

I am looking for some low profile motorola 2n3055 output transistors to refurbish a 3000-2. These were also used in the beocentre which used to same output board. If necessary I will buy a complete unit.Thank you in advance
