I have some questions. Now i am running 2,3turns primary and 900nF MMC, i have 7,5T reserve, so maybe i should use more tuns with 500nF capacitor ? Advice please

Hi Linas, you have to determine the primary "surge impedance".
Look here:
For example, for your big coil probably a surge impedance of 3ohm can be good... So, if your res freq. is around 60kHz you need a primary capacitance of 884nF and an inductance of 7.96uH

Hi Linas, thats beautiful coil you are building I have a question, are you planning on using a form of strike rail to protect your primary from streamers?

So i will remove 4 strings from MMC , ( 8000V 445nF ) because i can draw 250A peaks just with 24V input(and 10cm spark )) and here how my bridge looks now ( total 10.000uF of high current Rifa capacitors, new). It will be nice blow :D:D:D

Linas: Everything looks great! One can really see the amount of time and thought that went into the coil. Hats off, really! I can't wait for you to make the EUPECs start sweating.
If you don't mind me asking, where did you get that heavy wire and the snubber?

snubber ebay :) 5AWG wire from electronics store, it's audio power cable, like 4$/m (i can get and 20mm^2, but i guess it's pointless) And also, i made better bus bars job :)
And i guess it's final look of bridge ( 311V modification )

Incredible!
This is my favorite Tesla coil of any type ever! I see what you needed those brass bolts for, that is a great looking layout. You did the snubbers like me, with the brass nut brazed to the buss bar with the snubber screwed into it. I am glad to see that was not stupid on my part!
I am *so* envious, you have a real talent! Keep it up, i look forward to a new video!
