@@redloki_53 yes, i think it is getting time for a faraday cage😅 but this is not that easy in my room. I have actually no big problems with electronics. Only with my Smartphone, when i'm really close. Also the W-LAN data rate is a bit less while running the coil. With my SGTC i had actually really worse problems, but not with my VTTC. Interesting idea with the modulated pattern! Unfortunately i would have to make quite some changes, to do some (really good) audio modulations with that coil. i want to do that too and it got requested a lot😀 I need some time for that (and money) to build one. But i will make that in the future🙂

@ effects of some of this specific patterns would have possible astounding properties . Interesting also would be the effect of a fast rotating (output) Antenna.🙂 🤞🏼

@@Kangsteri thanks too🙂 Unfortunately i have nothing to measure the exact humidity and pressure of the air... but yeah probably in the future😁 I found out, that in the last 2 days, it was very foggy outside.. In that time, the coil was running a bit better.. Also the arcs got straighter with the double electrode. So i think today the air is more dry, and my secondary coil has a bit higher frequency because of less loaddown. When i add the long double electrode, maybe i load the secondary a bit more.

@@thomasgodwin3184 thanks for the feedback! Nice to hear that🙂 What type of tube do you want to use? Or do you want to build a SGTC?

@LutzSchafer Danke. Naja über den Wirkungsgrad bei z.b. einer SGTC braucht man auch garnicht erst anfangen zu reden😅 In meinem fall dient mir die verschaltung der pentode als triode, der Vereinfachung des ganzen. Der Oszillator verhält sich deutlich klarer/stabiler und weniger anfällig für unerwünschtes schwingen. Im "trioden" Betrieb weist die röhre weniger gain auf und lässt sich definierter mit einem kräftigen Signal aussteuern.

@@Sir-Dexter thanks 🙂

@pelos6945 for the feedback circuit? Im using 3 75w 230v halogen bulbs in parallel = 225w I have some normal lightbulbs too, but These actually behaved very different🤔 And at my older Videos im using resistors

@@beatbuzzergebastel haha ja an dem punkt war ich auch mal😅 Ich weiß noch, als ich für meine damalige große SGTC den kondensator für den primärschwingkreis aus Leydener Flaschen gebaut hab😆 ich glaub das waren 28 1liter glasflaschen😅 klappte tatsächlich ganz gut. Aber Das könnte man mit diesem kondensator nicht machen. Die koronaentladungen würden die Klarsichtfolie in 2 Minuten weggefressen haben.

@@jonschick oh yeah i wish i would have a garden to do that😄

@@ashercorbett8089 what do you mean with "rush E" ?

@ yk the insanely hard song on piano 😂 look it up it’s funny

@ashercorbett8089 ufff oh yeah thats crazy😄 now i know what you mean😄

@ lol

@@sweetdragon36067 The technology at the modern QCWSSTC's is actually a massive difference! With the right build, they acchieve arcs 10 times longer than the secondary coil..sometimes even longer! (Over 3 meter) Here in my case i have now about 90cm, sometimes a bit higher... for sure, for just 2 gu81m tubes it is good, but not near of the peak Power of a modern SSTC. Downsite of such a SSTC is the complexity, cost and the transistors can die instantly by the smallest failure. VTTC's are much cheaper, "simple" and tubes can handle sometimes up to 3 times of their powerrating for short duration🙂 Thanks🙂🙌

@@marvswelt2587 Thanks. My dad became a TV repairman in the early 1950's and remember all the radio's and TV's had huge tubes before the transistor was used in them. They had ridiculously more power(amplification) than a transistor. Good to see they are still being used. I'm really interested in zero point power, but doubt I will live to see the use. Thanks for the info.

@sweetdragon36067 oh these are beautiful memories i bet🙂 For me, tubes had something magical since i was a little kid.. and still today its the same. I can understand that they are outdated in the most applications today,.. but for some specific things, they are still today indispensable😀 I love them especially in guitar/bass amplifiers and audio amplification.

@@marvswelt2587 True. Fender Twin Reverb had incredible power and clarity. Great memories.

@sweetdragon36067 yes, i personally like the dynamics from tube guitar amps. The transition from clean to compressed crunch Sound, just with picking dynamic feels way smoother than the most Transistor based amps ive played. Also that sweet singing compressed clean Sound feels just really good🙂

@@jonlitchfield8888 thats a cool idea! I thought about that once...but the cores of these transformers are just so bad, i just use them like they are, and when they die, they die...dont want to spend too much time on them😄 Im searching actually for a bigger transformer, but cant find anything with 3kv voltage. . I think i have to build myself one, soon or later. Thanks🙌🙂

@IanDarley The toroid have just a littlebit bigger, to get the right tuning without Streamer breakout. But yes thats right, the most energy goes into the arc in my case.

@@cpunut oh yes🙂 thanks!

@@SkypowerwithKarl yes i have neighbours living nearby. This coil producing for sure interferences, but more in the spectrum of its own resonance frequency.. In comparison, a spark gap tesla coil would have much more weird harmonic frequencys and can really badly interfere with TV and W-LAN. I have actually no problems with that. I hear music over my Smartphone connected with W-LAN while im testing my coil😄 But i think (didnt tested it yet) it will heavily interfere with analog Radio at LW. For sure i would be much better to build a faraday cage, to reduce the possibility to stress some people out with humming on their radios😅

@ Over fifty years ago, a friend was playing with a huge Tesla in his basement. I had just been watching him for a while when I went home. About a mile away I spotted some blue vans with strange domes on top driving around. I made a quick stop at another friend’s house and called the first guy to tell him to knock it off. I’m figuring that he was making a lot of harmonic interference. Probably the only thing that saved him from pinpointing his location was his signal was overloading the searchers when they got close. By the way the second guy’s tv was unwatchable 😝 It’s a good idea keep metal in the vicinity away to help reduce harmonics/radiating elements or be in a Faraday cage. Have fun and be careful

@Skypowerwithkarl Haha, yeah thats actually something, im a bit nervous about😅 Especially because i Experiment almost everyday now for about 1 month with that thing😅

@@TriunfoGim thats a cool idea! i have 2 liters paraffine oil here! I thought about that before, but wasnt sure about the voltage rating of oiled copy paper or something. But i will give it a try for sure!🙂 thanks!

​@@marvswelt2587 Good, remember to use new mineral oil or use a vacuum pump (it can be obtained from an old freezer or an A/C compressor) in case of old mineral oil (due to air and moisture diffusion in the oil). Then, submerge it several times in heated solid paraffin (like candle wax) to seal it and give it shape. Make sure to wind these capacitors. Therefore, you will get a brand new old-fashioned capacitor maden like a pro (The ironing proces is for solid paraffine) but liquid parafine can be use for those wet papper oil capacitor of the old school.

@Smrts955 Oh yes for sure!🙂

@@beatbuzzergebastel 😃danke! Das war aber bis jetzt auch wirklich viel Arbeit gewesen🫣 bin schätze ich schon seid knappen 400stunden an dem Projekt. Aber der Weg ist ja das Ziel🙂

@charliemckay6681 😄thats actually a really nice idea!!!😃

@CamelCasee No, but someone said earlier, that he heard something too😅 Sorry i dont know where that comes from.

@@marvswelt2587 It's a ghost party being attracted by the electricity in the air 😆

@CamelCasee haha🤣

@SINHRO-FAZA yes exactly!😄 and now with the rolled Version it is cheaper than a capacitor that i can buy with the same specs! I dont have to wait for shipping and i need around 1 hour to make it😁 Thanks mate🙌

@@imeprezime1285 i dont know the actual secondary voltage.

@marvswelt2587 If you measure ground current input to your secondary you can estimate it: V=I*(2πfL). I -peak current of wave L-low frequency inductivity. This is gives correct result within 10% since current near peak is close to the sine wave shape

@imeprezime1285 oh wow ok, thanks!😀

@bassmaster9781 No i have the primarys of each series MOT stack in series and parallel together, to run it on 2 Phase 400V

@johanrheeder1640 Ok interesting!

@coreyworthington2797 i use actually 4 MOT's😅 2x2 in series in parallel. I use about 6uF now.. 3.6uF should be fine too! When you made an upgrade from Single MOT to 2 inseries mot, you have to tune the feedback circuit again, when you double the power voltage so the feedback voltage to the grids are around double too! In my case i reduced the feedback coil turns from 15 (for Single mot) to 8 (series mot's) Also there can be way more issues. Did you tested the MOT stack AND the voltagedoubler circuit before, if it funktions right? Maybe some internal arcing in the MOT's ? Phase issues? Are the capacitors still ok? Ground issues? Some weird arcing somewhere Else? There can be actually a lot of things😅

@marvswelt2587 thanks for the advice. I'll see what happens this weekend. I purchased 10 more .9uF microwave capacitors. I still need to make all the connecting wires. I'll try tuning the feedback coil as well.

@coreyworthington2797 it should definitely work ok with the 3,6uF But yeah more capacitance will give you more Juice 😄

@@coreyworthington2797 all microwave capacitors have a 10 meg ohm bleeding resistor build in and that reduce their efficiency

@@johnkelly7264 thanks!🙂 Hmm i dont know😅 i think electro boom have enough to do😅 i actually didnt heard of Tesla down under jet! Cool i check it out😁
