Picked up my first Yamaha gear yesterday: CR-620, TC-320, YP-B2, NS-5. I have a few questions that hopefully someone can help with. I've mostly got Pioneer gear, but this CL deal was too good to pass up ($25 for the lot!) The stuff was sitting in storage by the original owner for some time, so each piece needs some service. CR-620. Deoxit to the volume and Loudness pots cleared up some bad static. However, none of the four small lights are working for the meters and dial indicator. Where should I check voltage to make sure they are getting power? Seems strange that all four bulbs would be out, but possible. If I do need to replace the bulbs, what are the voltage ratings I need? TC-320: this just seems to need a new belt to the motor. Old one disintegrated and left black residue on the large turning wheel. Suggestions for getting this off? YP-B2: belt also disintegrated here. What is the appropriate belt size? I might have a spare that works, but want the correct size. NS-5: Tweeter on one speaker is not working. How do you get this out of the cabinet? I removed the hex head screws, but the tweeter does not just easily come out. There are three more screws holding the tweeter to the large black surround, but I thought the whole surround should come out? I want to check that there is not a bad connection inside before worrying about getting a new tweeter. Thanks!
