Hello All. I am fairly new here. Been lurking, reading, learning.... I have recently come into possession of some turntables. Dual, Garrard and B&O. I am going through them one by one. surface cleaning, checking set down points, change spindle function etc. A Dual 1209 is MIS-behaving. the tone arm will not release horizontal tension spring. it has about 3 inches of "FREE" movement from rest to about 2 lead in tracks width and then is spring loaded any further over the record. after tilting the player up onto its side to take a look under the hood, to no avail, I set it back down and low and behold the tone arm was completely free. plugged it back in and hit start. same thing again. then I tilted it again and this time manually brought over the tone arm to start and it worked fine.... Any ideas. I have looked for some time for similar issues ppl have had, but I don't think I am using the correct terms.
