tech help - Seeburg STD160 'rumbling' sound
My Vogue II has a new trick it started last night, it gets through 1/2 to
2/3 a record and the volume will go up & down and it will make a loud "rumbling" noise out of the speakers. I rejected the record (for fear of scratches), but checked with other records and does the same thing. I replaced the needles about a year ago, but I don't use it that much so I can't imagine those being shot (but they were those knockoff yellow needles). Any thoughts? |

'Sounds like you have a stiffened, or hard, drive motor coupler. It's
located just above the only motor on a Seeburg mech. The coupler is made of rubber with brass end caps and is held in place by (allen key) set screws, two per shaft, meaning there are two for the motor shaft and two on the worm screw or drive shaft. What's happening, is that the stylus is 'feeding' the vibration from the motor back to the amp because the damping effect is not there with soft rubber. Also of note are the actual motor mounts themselves. Hope this helps! Cheers, Steve |

I was thinking, this sure happened all of a sudden - but then I think I haven't run it for about 4-5 months -so I guess it could have stiffened up by then. |

ups.com: Go to www.victoryglass.com Look for part numbers 49-1947, (coupler) and 49-5873, (motor mounts, 'donuts') Cool, thanks! Before I do order and replace items, is there a way to check the coupler (test of some sort)? It probably needs to be replaced anyway, but want to make sure... |

You can remove the coupler beforehand and check to see if it's stiff
and/or cracked. If so , it's definatley done! If you can twist it, feels like soft rubber and no cracks appear, it's good Barnhart Pinball wrote: "Stevie D" wrote in ups.com: Go to www.victoryglass.com Look for part numbers 49-1947, (coupler) and 49-5873, (motor mounts, 'donuts') Cool, thanks!
