Re: [TCML] On scaling up Tesla coils



I used to run 4 OBITs in parallel, and they are very similar to NSTs, I 
ran 5 once on a Jacob's ladder but that is the extent of it.  I don't 
think you can ever max out the number of transformers, until you could 
have paid for a pig with the number you have bought.  Could be wrong though.
