Jonnantais: Your siting the fact that Lencos mantain speed accuracy over long periods of time does NOT invalidate my hypotheses that the expanding universe effects turntable speed. The Swiss were genius enought o realize this effect and took it into consideration when they designed the Lenco. The Lenco's idler is much thinner and lighter weight than other idler pucks, it is less subjected to this continual expansion. The idle's narrow size and small mass reduces the effects of the Universe Expansion. Also your Lenco idler may be the non-metallic type that is less affected by the expansion and also immune to the eeffects of space curvature. In addition, the Lenco idler is unique in that it is at Right angles to the platter, thus it is in a different plane and dimension than the platter. A expansion of an idler in this configuartion will has no effect upon rotation speed.
The effect of the Expanding Universe on turntables
Since the Universe has been continually expanding after the Big Bang, then it stands to reason that all objects have expanded also , but not nessecarily in proper proportion. This means that the turntable you buy today will actually be larger(and contain more mass) at some date in the distant future (20 years?). I have now discovered why I have never had a used turntable (over 100 turntables) that is on accurate 33&1/3 RPM speed, even with quality synchronous motors. This phono-nomenon can only be attributed to the fact that all the motor parts and the platter are now larger and more massive than previously and thus the ratios of pullies and gears is no longer as designed (in the past), this is the only explanation I can offer as to why the speed of old turntables is faster than when new(by a small percent).It also explains why many older mechanical devices never work properly , no matter how well maintaied and repaired.
