No thin paper gasket. Just the thick insulator gasket.
Thremoquad gasket. There is also an open hole version of the Thermoquad gasket, but as you can see, the Thermoquad gasket has a thicker back wall. Using the Queerdrajet gasket on the Thermoquad will result in a vacuum leak around the back of the secondaries. Most stores will try to sell you the wrong gasket, because they want to stock as few parts as possible.
