I blew up my stepuptrafo's, now thats horror!!
I can get use to the flashes before your eyes when I touch the outputs from the trafo when it is playing music....

Yes you are quite correct, if you provide a path from (-) power to (+) power be it DC or AC you have effectively provided a return path that will give you a nice electric shock.
However your second point is - again- simply wrong.
IF you grab HV and you have no return path, be it ground or a termination of opposite polarity there will be no current flowing, so no shock.
I can tell you categorically that I have personally stood connected to a rather high voltage and reasonably high current source in the form of a very large Tesla Coil while NOT connected to a return path (be it ground or not) and suffered no electric shock. If you had been connected to ground, you'd likely be dead given the power input to that particular coil. No return path, no shock. Ask any bird on a power wire. Return path? Ask any fried squirrel about that part. 😀
DON'T TAKE ANY CHANCES AROUND HIGH VOLTAGES, period
Hope we've fully clarified this point now?

The point of this thread is not about what happens to birds and squirrels on power lines. And it isn't about how high frequencies propagate in the vicinity of a Tesla coil. None will argue with your mastery of those subjects.
The point of this thread is "can I get hurt building electrostatic speakers?" The answer is a definite YES. Your continued insistance about how you can touch HV lines without getting zapped is merely adding confusion to rank beginners who might read this stuff and assume they are totally safe because some guy said "you can't get zapped if there is no path to ground."
Just in case there are any non-electrically educated people reading this thread and wondering if they can get hurt building electrostatic speakers I'll say it again- no matter what you read about being able to touch high voltage lines, grounds, Tesla coils, and birds, and squirrels, YOU CAN GET HURT OR EVEN KILLED WORKING ON ELECTROSTATIC SPEAKERS. BE CAREFUL.
You're obviously an intelligent guy. Someone of your intelligence can obviously see the potential danger in ESL construction. Do what an intelligent person would do and let this thread die its long overdue death.
I have nothing further to say.

This is an interesting thread. I'd just like to add a link to an excellent and thorough webpage on electrical safety which I believe covers all the basic safety points raised here (and more).

Scaring people by making a blanket statement that ESLs are extremely dangerous doesn't serve the "rank beginner" at all.
Teaching them exactly what, where, and how the danger exists, and to what extent does serve them.
And, as I mentioned, any piece of standard tube gear offers substantially greater dangers and risks than a typical ESL speaker.
Sounds to me like you may have gotten knocked on your rear by an ESL at some point? 😀

Heh, reading through the whole grounding argument is pretty funny. True you do need to be gounded to be shocked, but it doesn't take much to be gounded . You can go grab powerlines and HV transformers all you want thinking your shoe isn't grounded. Helps us cleanse the gene pool...😉
Hi,
As i know,
Human has some capacitance , so you dont have to be grounded to get shock.
However , this type of shock is not very dangerous.
It is dangerous to touch both the stators the same time.
I did it, and still remember.
However , AC mains is probably more dangerous , because it can supply much more current.

Hi,
standing on earth means, that You are grounded! So working with potentially lethal voltages You should always wear shoes with proper insulation, e.g thick rubber soles.
Grounding means, that a potential can develop between the source and ground thats able to let a sufficient curent flow. With Birds on a wire there is no contact to ground in first place and the potential difference between both their legs is too small to have a sufficient current flow. A difference occured if the bird would touch 2 different wires at once (e.g two stators)! Then we´d have instant chickenMccurrent ;-)
While its not that easy to get shocked lethally with an electrostatic, the chance of getting nasty shocks is given. Mainly at the cascade of the HV-supply, and open soldered points at the Tranny and the stator-signal-connections and -not to forget- the mains supply line.
As soon as the stuff is incapsulated in a insulating housing, everything is fine.
