T>> T>> What is tank circuit ? In Tesla work, there is none. It's an old (and for that matter current) radio/rf term. It's argot for the primary resonant circuit in a power oscillator. So, by extension and analogy in Tesla coils (if you absolutely insist) it's the primary coil and capacitor combination and associated circuitry. T>> Should the spark gaps be connected in series or paraller ? Definitely. This type of question could provoke fist-fights in Tesla bars (if there were any Tesla bars). It'll work either way -- but better you should discuss the abortion issue for the amount of controversy this topic can provoke. BTW - Anyone for opening a Tesla bar? A bar with a Tesla/high-voltage theme? A few Tesla coils of various sizes, a couple of Jacob's ladders, maybe a plasma globe at every table, some theme drinks? T>> What is safety gap ? T>> It's a spark gap set slightly wider than the working gap(s) -- so if excess voltage develops the safety gap will conduct and lead the voltage harmlessly away, usually to ground (but sometimes merely around that which one wishes to protect). How many of them to use and where to put them is another abortion-type question. You're sure to draw "sparks" on this one. T>> How to prevent high voltage spikes striking back to wall ? T>> Well, a =real= coiler would move the wall, or knock it down. Else, - Don't run so much voltage (you have to live within your limits). - Work outdoors. - Pray a lot. (And go to church every Sunday). - Erect a grounded, conductive shield in front of the wall. Many use chicken wire on suitable supports, but if you go this route, better combine this step with the one directly above. T>> -Calle Robert Michaels
