Yes, I am sure that it has autostop functionality. The stock cart on this set was also a ceramic cart which tracks on the heavier side. I think it was either GP205 or GP215. Am not sure about if AG3404 will fit as its a plug type mounting system.
The mount looks same to me
But i read somewhere ceramic creates relatively high voltage (200mv) than magnetic (15mv). So just a little confuse if it will work or not.
If anybody here with 832 can help me by sharing interal pictures of 832 for auto stop functioning mechanism i will be grateful. Thanks
