NSM Concert 240 III (ES4) alignment help
I am working on my NSM Concert 240 III (model 240-3), and have a few
questions for the list. I bought this jukebox advertised as non-working. I powered it up and found that the arm that picks up the records was out of place and the record spun slowly. I fixed the arm and cleaned and relubed the "platter" and it pulls the proper record and plays it on speed now. One issue with the mechanism remains, and that is that one side of the record starts with the needle half way into the record, while the other side starts right at the beginning of the record. The "bad" side looks like it will start properly, but as the needle approaches the record, it is being pulled towards the middle of the record. I can't see what is pulling it. Any ideas on where to look? I also see that the bracket where the springs attach to the tonearm appears to have been reshaped as well. Can someone supply me a photo of how the original bracket looked on an ES4 mechanism? I haven't been able to find a service manual for this jukebox in the US. Are there other models that use the ES4 computer and mechanism that I could substitute? Thanks for any help. Jon Scaptura |
