[QUOTE="Qualityten, post: 760610, member: 17776"] I worked on a faulty NAD 7020 with the help of members of the UK vintage radio restoration forum in Dec-Jan. The thread is here: http://www.vintage-radio.net/forum/showthread.php?t=132080 If you are handy with a soldering iron and can check your work with a circuit diagram, you should be able to replace all the capacitors for not too much money, though quite a bit of time. I only found one faulty capacitor, but the results are still very worthwhile. The suggestions made already are all valid, as the quality of assembly of these units was not very high and a dry solder joint is possible. I reflowed all the joints when I recapped mine. If you want to pursue a remote fault check, you would need to describe the problem accurately as possible. I admit that's not easy. As to your question about the pin, it would depend where the pin was lying on the circuit board. [/QUOTE]
