Hi Verpies
Can you please say some more on this? Why CW-CCW center fed windings don't result spikes?

Center-fed windings cancel the undesirable circumferential current because half of the current flows in opposite circumfererential direction to the other half.  (there is even a patent where this issue is central).

An even number of back&forth layers spanning the entire circumference cancels the circumferential current, too.

To keep the desirable toroidal current in constant direction, the turns have to be wound in opposite toroidal directions on the two sides of the center tap.

Circumferential current is co-responsible for leakage inductance together with narrow windings (that is: windings not spanning the entire circumference of the toroidal core).
The leakage inductance significantly contributes to HV spike generation, so minimizing it, minimizes the spikes as well.


In the past, I made drawings of narrow windings and circumferential current - look in my attachment list.


P.S.
The HV spikes generated when the current in the primary winding is interrupted while the secondary is unloaded, can be recycled back into the power supply using the lossless clamp technique consisting of a double wound primary winding.  This technique works the best with full windings and properly cancelled circumferential current, i.e.: even number of back&forth layers (or CW+CCW center fed winding). 
If these 3 conditions are fulfilled then spikes disappear and the dissipative RC snubbers can be omitted altogether.

  12R06 are the diodes mentioned on the diagram (below) made by Ruslan. 
You may have to look for an equivalent UF series diodes. As there is no data sheet for the 12R06.

  Thanks Hoppy, I could use some of those diodes, as well. Ebay has them.
  I checked to see if I had anything like those, but I don't.
  So, I'll have to order 4 of the STTH1206DI diodes, to build a 4 diode full bridge rectifier on a heat sink, and, add that black square capacitor that Ruslan is connecting to them (12uf, I think).

Its quite common to find that the first few characters of a component coding are left off of circuit diagrams / component lists.
