Hi all, I’m new to this forum. I bought a beautiful 4002 a year ago that is in great cosmetic condition and had not been used in many years. I went through the usual cleaning and lubricating process that Beolover suggests and now is functioning really well. However, I have two questions: 1. It functions perfectly other than it appears the sensor doesn’t detect if there is a record on the platter and will drop the needle regardless whether there is a record or not. The light on the sensor arm is working. I have borrowed an oscilloscope from a mate, however, I don’t know how to check the sensor voltage. Any help here would be greatly appreciated (I’m a furniture maker by trade - not an electrical engineer - so I’m not too familiar with electronics). 2. All the capacitors, relays and transistors are the originals. Is it worth preemptively replacing these? I would love to learn how to do this myself if there are any enthusiasts in Brisbane, Australia that would like to help me. I can offer a carton of beer or your favourite whisky ;) Alternatively, I could fashion a new solid timber trim (oak, walnut, rosewood, or teak) for a 400X as payment. Thanks everyone! Christian
