5 Watts in 60 Watts out ...

Cheers penn.

Yup, that's how i did it.

I'm just looking for a smoothing cap now, will 450 Volts @ 150 microfarads be ok ?

I'm too new to comment on that, but I think you'd need the frequency to nail the cap size down.  That aside, if there isn't a measurement error there, AND, if your meter isn't going crazy from either the frequency or the proximity of the magnet, that implies something like 5000% OU, and this looks like a typical circuit I've seen pounded to death around here.  I'll pore over the original thread you linked in the original post.

After you throw in the output cap, would you mind making another video?

Oh I See !

So my power is calculated using the load resistance NOT the coil resistance ?

But when i calculate it without the load the proper way is to use the coil resistance isn't it ??

Hi Gaz,

No, you cannot make a power calculation without having a load.

Unloaded, you may only state your output voltage.

Also, I agree with Void, in that, frequency plays an important role in measurements.

Well if the correct calculation is with 66 ohms then that would be a very large power output.

I'm just gonna solder this cap on (when i find my glasses !) and see if it self-runs.
