You get the (secondary/primary winding ratio) squared times the capacitor value when you place it on the secondary winding. If you choose to put it on the primary you get 1 x capacitor in value. As Tony describes, there are two LC circuits in effect. A parallel and a series circuit. The Parallel LC circuit sees 1 x capacitor in conjunction with the inductance of the secondary winding. The series LC circuit sees the primary choke inductance plus the primary widning inductance combined with the winding ratio squared times the capacitor - if placed on the secondary. If you place the cap on across the primary winding you will need a larger cap to get a good result. wronger than a phone book full of wrong phone numbers
