In the bowl of a KitchenAid mixer with the paddle attachment, beat the cream cheese on medium-low until smooth, around 1-3 minutes. Scrape down the edges as needed with a spatula.
To the smooth cream cheese, add 3/4 cup sugar and the salt and beat until incorporated, around 1-3 minutes.
Add the rest of the sugar and beat until incorporated, around 1 to 3 minutes.
To the cream cheese mixture, add lemon juice, sour cream and vanilla, then beat for 1 to 3 minutes to blend well.
Beat in the eggs, two at a time, until they are just incorporated, around 1 to 3 minutes.
To the inside of the springform pan, use a basting brush to brush the remaining 1 tablespoon melted butter.
Place the springform pan with the pre-baked crust onto a rimmed baking sheet.
Carefully pour the filling into the springform pan, using a spatula to level out the ingredients until smooth.
Place the Cheesecake with the pan into the oven in the middle rack and bake for 10 minutes.
Then, without opening the oven door, lower the temperature to 200 degrees Fahrenheit, and continue to bake the Cheesecake until the temperature reaches 150 degrees Fahrenheit, around 1 1/2 hours.
Once the Cheesecake reaches 150 degrees with a thermometer, remove it from the oven and rest it on a cooling rack.
Run a knife around the edge of the pan.
Cool the Cheesecake until just barely warm, 2 1/2 to 3 hours, then run a knife along the edge of the pan again.
Wrap the Cheesecake tightly in plastic wrap and then place it in the refrigerator until cold, around 3 hours.
To unmold the Cheesecake, wrap a wet and hot towel around the springform cake pan and let it sit for 1 minute.
Remove the pan edge and then slide the cake onto a platter. Then let the Cheesecake rest for 30 minutes before serving.
