We got the 82th, 86th and 90th, all with more than 300 days warranty left which means they have just left Bitmain's warehouse, , the 140TH is the XP version of the S19 and is a different model, it is pretty normal for Bitmain to still manufacture old gears that they can still sell, also just because they are labeled new and still under warranty -- it does not mean they were recently manufactured, they could been sitting on the shelf waiting for a new buyer.
