Wondering here, what the purpose is of the small limit pin that hits the front of the stylus when the needle tilts upward a bit too much in front? I have a number of somewhat warped records and that pin is the cause as far as I can tell for the stylus to be cutting in to the run off area scratching the surface. I notice the Edisonic head does not have this feature and will play though with out damage. I am curious if it just couldn't be filed down to prevent that digging in on the center or a mildly warped record.
Any thought on this here?

Re: Purpose of the limit pin on DD Reproducer.
I gave it some thoughts and maybe it was initially intended to prevent the end of the stylus bar to touch the record surface, something we know from the earlier Model H reproducers.
Nevertheless, it very doubtful that is this way the record would suffer less - I'd rather go for the opposite. I have always wondered about the whole diamond reproducers, both cylinders and discs, why they have such little tolerance. The cylinder reproducers can be really awful when the record is out of round. I always mount the reproducer about 1mm higher than it would normally fit, just to save the record.
