Thanks Hoppy, i appreciate it.
I saw somewhere in my scrap storage a similar choke. I am going to search for it. 

Hi Jeg. I already posted a comment on your kacher circuit question yesterday to you.
Did you not see my reply?

Guys,  take care NOT to use a lab PS when tuning/testing your Kacher, use a battery or a simple 12/24V PS.
Last night one half of my double PS went out with a big bang while tuning my new kacher 
There is loads of RF going into your PS with the above result, the same warning i did read on the Russian forum last week or so.

Hi Itsu. That is likely why they have the special choke and filter caps in the kacher schematic.
I also blew one side of my bench power supply as well a couple months ago testing driving a
tesla coil with a FET pulser circuit. I fixed some components in the power supply, but the current
limiting is still not working correctly. Something still blown in there that I haven't been able to find. 
All the best...

Right,

i can see/measure these damaged parts, but there could be more invisible damaged under the hood 

2x MOSFET
4x 15V zeners
some fried PCB traces

Yikes. It helps in finding them when components are obviously blown like that,
but can be trickier to find other blown components that do not have outside surface damage.
I will have to do circuit tracing to see if I can find what is wrong in the current limiting circuitry.
Not always so easy trying to do that when you don't have a schematic. 
All the best...

A close look at the Ruslan Kacher board suggests to me that there is one base to emitter protection diode and a diode between collector and ground.
