Alright, so after ordering a completely wrong type of NST PSU I got a proper iron-core 6060 unit coming.
Now here's a problem I haven't thought of before. I live in a relatively small apartment and I probably would not want to build a TC that would draw 6 foot sparks or anything more than a foot long.
How small can I make a NST powered SGTC for practical use?
I noticed someone has made a briefcase type of SGTC in the Projects section but no plans or specific parameters were posted. That's probably the scale of a TC I'm going for.

My small NST SGTC (5kV, 30mA) was built on on a 1'sq base, and stood 2.5' high, including an 8" sphere TL. SG was single gap computer fan quenched, and only produced 10" streamers, good enough for me on my first attempt. MMC was 2x4 47nF 2kV WIMA caps, for 23.5nF @ 8kV, so nothing too big.
There are SGTC calculators online (java based and downloadable) you can use to help design it. I factored in my NST and worked the numbers will I got a desired streamer length, and built that.
Others will tell you to understand everything before you build, and that's good advice - but I was impatient. Guess I was lucky mine worked...

well,I found a web site (this guy really did build this) but it might be an idea as to where to start out...
Do a google search for "Trashy tesla coil"...built out of junk,but,it might give you some ideas as to building a smaller coil that won't burn the place down
