I used a safety raiser, too. Worked fine on the table it was on. It is now in the box with all the accessories and won't go anywhere but onto a table I have. I've gone through the time of jumping up whenever a record was over and now have an SL-1600II to do the auto/shutoff duties when I'm to attending to the rig but I still prefer manual tables and will put the AT6006 onto the TD-125/SME I just assembled from parts. Plenty or room for the device not like a few of the other tables I have had over the years.
It in not that they are proud of the unit, there is that demand for a less common device that saves stylus wear and these styli are getting much more expensive. If everyone knew about the Q-up or whatever is available new today for about 60, twice the price of a new safety raiser back in the day, maybe the raiser's price would drop to double digits. But adjusted for inflation, that 30 is now about 85 so there is that.
The manual for the AT6006 is on vinylengine.
