Have you got a multimeter to test the output?

"I saw it in youtube"
There's no oscillator function in this, which is what it needs.
Something like a capacitor is needed - the thing is wrong or incomplete.

There is, I think, if its wired right, that's what the feedback connection should do, if everything is phased right.

It looks all static DC from my chair. Would a circuit like that not need a "kick" to start it?

Remember, you can build RL oscillators as well as RC.

There's no way to tell you without more details. Where did you get the circuit from ? What's the transformer wiring ? One false move with this circuit and the 3055 is toast.
