Greetings everyone! It is my first post and I am from Latvia. It is my fifth tesla coil. I made it from some parts from previous coils and another “garbage”.
Secondary: 30 x 7,5 cm ( ~11 x 3 inch), with 0,27 mm wire;
Ballast: MOT primary;
IRFP 460, protected from source to drain by 13 1,5KE33CA in series;
Interrupter – Power supply controlled by triac and MOC3063M, duty cycle – 10 - 100 %.
Streamers about 25 – 30 cm. It’s possible to make them bigger, but transils and mosfet will become very hot.

Some sparks:

Great results, I guess it is never too late to build something simple, I should give the slayer a go soon :)

Great work. The mechanical construction is also beautiful. What kind of a power supply are you using?

Power supply is half-wave rectifier (mur1560), connected to 220 V AC.

Same here.
Made a test coil from a cardboard former, didn't expect it to work but it seems stable and locks on to the MSF signal somehow.
Was an excellent demonstration of how not to build an MSF receiver because it also picked up LED lighting and someone's NFC that they had turned on by mistake.

Tuned using Peak Atlas LCR, although the coil did drift a fraction of a percent when dried out after Superglue encapsulating this is swamped by the heat induced resistance changes from all that copper (1600+ turns salvaged clock wire)

EDIT: Latvia? are there any other HV enthusiasts/coilers there?

I once spoke to a guy from the Ukraine about one of my projects, apparently they might know Kreosan!
