The schematic for the stock power supply is here

The transformer coils have the Turns listen, times the strands that are in parallel.
The other number is the layer counting from the bobbin, I also used it as a phase dot, putting in on the side I'd put the phase dot on.
I'll draw out the primary circuit in a bit.
The driver IC is a KA1L0380R, fixed at 50khz.... at this point I'm desperate to get some kind of power supply working so I'll just stick with this not-ideal choice, I know it was working.
After looking at the numbers in every orientation there doesn't seem to be any correlation between anything and the V/turns ratio.
I'm just worried that the voltage will be WAY off for the HV winding, I'll use the heater winding for the voltage refrence so that's not a problem but the HV winding would be a problem if the V/T ratio suddenly jumps up or down as the turns go up.
