Tesla's Magnifying Transmitter "Replications"

Yeah the many turn coils those guys use to get the big arcs chew power like candy,
the resistance of the wire would lower the "Q" quite a bit. So they will make a lot of
voltage but the wire will get hot with extended use.

The less turns and resistance the better for long use. For Arc displays with long
arcs a lot of voltage and power is needed.

A true Magnifier should be able to run 24/7 except for maintenance to the spark gaps ect.
One of those would catch fire or melt the insulation after some time unless cooled somehow
and waste a lot of power. They are like big doughy bells hit with several sledge hammers to make them ring loud.

My transformer has 1 mm wire in the secondary and the Extra coils which
gives it about 4 Ohms resistance if that. The primary is two 6 mm tubes in
parallel basically no resistance in the primary coil.

The power wasted as heat I think could be calculated by the resistance, the oscillating current and the frequency.

Can I ask, what is your input power ?

Can you use an energy meter before the variac to see the power factor and the input power ?

How much voltage are you using on the primary ?

Is your spark gap a multi tube design in the canister ? Sounds nice the gap.

Stay safe.

Cheers

Input power is 60 v, and the ammeter bounces as though it is surging like waves,
on start up the watt meter says 38 watts, then it starts flashing and reads random numbers
i am having issues grounding the beast, but am going to do some outdoor tests hope tonight.
ultimately i want to return to the DC class E push/pull mosfet driver with the prescribed frequency from the start.

it has been said that "if one only uses capacitive ballasting, there can be some frightening current exchanges and uneven operation will occur.
But with resistive and capa/inductive ballasting, long run times at high power are possible"

im using about 5-6kv on primary, and the spark gap is just carriage bolts with round ends. i really mean to cool them, but i am also thinking about vacuum chamber or inert gas.
but if i can eliminate the gap with some more efficient way, then im gonna try it. i do have some IGBT bricks, but dont know how to use them
i just dont know if an OLTC will give me enough v to the primary, anyway, i want to make this more solid state like your Armstrong Oscillator

yeah big pourple/violet streamers are an indication of high current in the arc i have read.
hey you know how Tesla said that "the secondary will always act upon the primary" (bemf) .."not so with extra coils"..
so i wonder about putting a little step down primary around the free resonator, to see if i can draw from it without bemf? or maybe im just too tired right now hehe
will have more soon, and more improvements on my colorado springs model.
i have read a lot on magnifiers lately and it is well known that Tesla sacrificed a great deal of efficiency by allowing off axis inductance to creep into his system, a possible improvement was the 20 ft dia pri/sec demonstrated by famous Magnifier Project 13M, thats why i wanted to see if my resonator was just reacting to induction, or is it able to resonate from the single base connection alone, so i plan to stick with Tesla's extra coil, but may use a skinnier master oscillator.
gotta compare a few more to see what im gonna land on

I hope your health is getting better, we need ya!
