You're probably referring to this thread, where a fella in England describes how he replaced a HV winding with a tripler (although in a B&W set).
See post# 18.

Some translations of terms would probably help:
'Overwind' = HV secondary, 'donut', 'tire'
'EHT' (Extreme High Tension) = HV to CRT anode
'LOPT' (Line Output transformer) = Flyback xfmr.
'Line Output Valve' = Horiz. output tube

Note that he had to add some capacitance to the primary to compensate for the capacitance lost due to the missing 'donut'.

Earlier posts in the thread describe the perils and pitfalls one would encounter trying to actually rewind a flyback.
