Did you say Vacuumatic?? Grandpa had one too:
The arm is extra wide to accommodate the little vacuum head (with brush) mounted at the front of the arm, not to mention the vac hose that extends out the back. Only this one is a ringer. The original turntable was replaced ca. 1977 and eventually lost. The one you see here was aquired just weeks ago, removed from a model that did not have the vacuum motor. The knobs are also not correct; they should be the same knobs seen on the V-Ms with cobra arms that were being put into Zenith stereos of about the same time frame. I would love to restore this set. I'll see if I can get a line on a schematic...could you possibly get some detailed photos of the underside of the arm?
