Interesting. Makes me wonder about the authenticity of my 602 as it does have the auto stop (unless I'm misunderstanding the NS feature Greg is talking about). I've yet to pop the motor board off, but so far everything looks "Columbia" (from needle cups, to hinge hardware to tonearm & reproducer) How does one know if one has the non-set? (Newbie question, so please forgive me.*)
As for the auto stop on my Grafonola 75 (or 85 - the storage system differentiating the models was missing, but I'm rebuilding one), that has never really "worked" as it stops two or three times per record when engaged via the motor plate switch. Perhaps mine isn't calibrated correctly or, as Greg mentions, it's just too difficult to maintain (for service as well as consumer). *I finally tracked down the Baumbach book (I had to order from Amazon UK, shipped from New York!) so hopefully after it flies all over the Atlantic, I'll have more info - if it's there at all! - and less newbie questions. :-) On 1/9/13 6:38 PM, "Greg Bogantz" <[email protected]> wrote: > I have the models 611, 613, and 810 which do not have the non-set >(NS) >auto stop feature, and I have never seen any of the VivaTonal models that >included the NS feature.
