In the real world
@ 120 VAC in you get approximately 300 VDC out.
@ 80 VAC you get approximately 130 VDC.
Note:
120 VAC from wall gives only 260VDC where as hooking up to my auto transformer stepping up 40 VAC from Auto transformer to 120VAC through step up transformer then to circuit gives the 300 VDC output. This is something Im not understanding.
Shake the phone to inject noise and start the oscillation of the capacitor and you see the multipling effect
