I have got a 20 year old sony mhc nx1 out the attic, turned it on to find amplifier fine, but all belts turned to blackgrease and got in all sorts places in both the cd jukebox and the cassette deck., Ive cleaned the pulleys and other relevant stuff on the cd unit and have belts so far so good. The cassette deck requires me to pull two capstan assemblies off, to properly clean behind them and the pulleys. I have not idea how to remove a captsan and flywheel but i want to do it. How do I do this properly. Any advice on techniques, spares or tools would be a great help thanks for reading
