I have tested this kind of circuit: in short it wont work with this simple design: the primary detune when you load the trafo, thus killing the resonance and the Q factor, we must find a way that when you load the secondary it does not detune the primary... Here it's another question...

Your diagram implies that the transformer coils will have cores. This will interfere with your goal because the cores will saturate and also will heat up robbing energy from the coils. May I suggest that you consider closely-coupled air core coils? You will need a lot of wire and/or a very large capacitor if you want to resonate at 60 Hz, though. Think a 1/3 scale model of Tesla's Wardencliffe installation. But if you can accept higher resonant frequencies, you can work with smaller devices.

The basic way to tell if a secondary is in resonance to the oscillations being fed to a primary is by monitoring the voltage rise using an oscilloscope as the primary frequency is swept through likely values. The resonant frequency can be calculated for any coil if you know the length of the wire and a few other parameters, but roughly, it's the frequency corresponding to 1/4 the wire length. In other words, if you have about 2.5 meters of wire in your coil, that's 1/4 of ten meters, which corresponds to a frequency of about 30 MegaHertz. f=(1/wavelength) times the speed of light c, so for a quarter-wave resonator use 1/4 the wavelength in wire.

To test a coil's resonance you just hook the secondary coil, a 1 meg resistor, and the oscilloscope together in series and sweep the primary across the approximate freq as calculated from the wire length, or simply guessed at. As the coil goes in and out of resonance you will see the characteristic voltage rise.... VRSWR it's called: voltage rise through standing wave resonance. What happens is the quarter-wave coil acts like a whip that's free at the far end and when you "crack the whip" the far end (representing voltage) can swing much wider than the "cracking " stimulus.
There are several videos in my channel showing triple coils, air core, in resonance and some interesting effects from them.
