Not cheap... :'(
What you get is the Voltage Multiplier PCBs... (and probably
empty tubes)... :-?
These HeNe 10mW tubes kick-start with 10,000 to 20,000 VDC...

1200V at 0,054A means 65W, which means you will need 240V at less than 500mA (about 300mA) in the primary of the transformer.
1200/240 means a 5/1 ratio, so a 240 to 48V @500mA transformer in reverse will do the job, if i'm not missing something. And those are pretty cheap as far as I know...

Yeah... what you are missing is the insulation rating of the Xfo windings... you are putting 240vac on
the output windings rated at 48vac and you are subjecting the input wings to a 1200vac voltage
when they are rated for 240vac...
Your cheap solution could burn down your home if it doesn't just blow after shorting out the
coil windings.... :'(
Yeah... I know... it looked good on paper.... :

Yeah... i've been partially owned...
It wouldn't probably burn nor explode, maybe just a spark and some smoke...
With the proper protection devices (which at least here all houses have) i think it would be worth to try... of course outside.
Once i accidentally short-circuited the AC input of a great PSU i had... because i dropped a metallic thing and...
But the only thing that happened was a big spark and some "burning" inside the PSU, enought to trash it...
But it didn't exploded or burned.
