   Itsu:
   No, I haven't gotten my resistors for the snubbers yet.
   I have been trying to kick into activation the 27.3KHz sweet spot, but I have not been able to do so there.
   The Kacher is what activates it to go into the chaotic mode.  And it won't just go there without the Kacher's HV pulses.
And without going into that special mode, there is NO effect, or just a little effect noticed.
   At the lower frequency sweet spot, at around 16.3KHz or so, I can make it go into both normal and chaotic resonance. But, like I had mentioned, the one fet gets really hot very quickly, as the peaks go over 250v. The left fet is the one with higher voltage peaks that gets hot, while the other fet never gets hot.
   So, I guess that it's a matter of balance, to get the maximum effect, but without burning the fets out with over-voltages.
   I may get my snubber resistors tomorrow, if I'm lucky. We'll see.

Nick,

i know that you do not have your ordered resistors yet, but as your present Oleg snubber is connected up wrong, it still might work OK with
the present resistor after connecting up the Oleg snubber the correct way.


Anyway,  take your time, no hurry here, get to know your new scope first.

   Itsu:
   I may be confused about the pin out on the MUR1530 that I'm using. As well as your diagram.
   So, I can't seem to find the right way to connect up the Oleg snubber.  I may have the polarity wrong on those diodes, but I'm not sure what's wrong. As I can't tell from looking at their data sheet.
  I'll post a close up of the snubber in my next post.

This pinout is standard for diodes in the TO-220 package.
