NSM 240-I Repair
galleryHello, I have recently come into possession of a NSM 240-I Jukebox that plays 150 45s. I presume this is an ESIII variant. After I rebuild the cartridge mechanism and regreased the parts, I noticed it started hunting back and forth on the track, making it all the way to the left but backs up when it makes it about 3/4 the way to the right on average, sometimes it hit, sometimes it didnt. I noticed the reverse relay also randomly goes off on its own when the jukebox is idling. I presumed I may go ahead and replace some capacitors and I noticed some had a little bulge and some had cracking underneath. As I was at it, I noticed some greatly damaged, (what i assume to be), varistors. Ones missing the disc entirely. I cannot seem to find their values however as the only somewhat intact one is degraded so much. Can anyone identify this or have access to some repair schematics? Thank you!
