the ouput of a jt is pulsed dc correct ?
so what if we put this into a step up transformer.
...
now if we take the output of that step up transformer and then do the reverse step it down but the same way we steped it up.
if i understand transformer right this should give us more ampage ...

WT
...more amperage than what?
...and then what?

well with the jt we loose ampage for voltage i was just thinking that doing the step up then step down should give us tha ampage back after all this is what power stations do

maybe run the jt off a earth battery after the step up and step down we might have the voltage with userable current

Think it through more carefully. There's something not adding up there.

what the fact it takes current to start with?

Check your transformer theory again.

With a step-up you increase the voltage, and decrease the current. The opposite is true when you step-down. So you are back to where you started (high voltage, low current), minus losses.
