A good source of theoretical and practical information is the book 
"Modern Tesla Coil Theory" for $20 by Duane Bylund, published by 
Tesla Book Company, P.O. Box 121873, Chula Vista, CA 91912, phone 
1-800-398-2056 (free catalog available).  The Bylund book is an 
8.5"x11", 140 page spiral bound book with chapters on:
    1. RLC circuits
    2. Transmission line theory
    3. Tesla secondary coils
    4. Capacitive discharge Tesla coils
    5. Vacuum tube tesla coils, and
    6. Transistor tesla coils

The book is somewhat technical in places, but not overly so.  Duane 
also suggests practical tuning and troubleshooting tips, most of which 
can be used with a minimum of instrumentation.

As for parts resources, look in the yellow pages for neon sign 
companies; they will probably have used transformers for sale.  Other 
valuable resources might be your local amateur radio club and any 
hamfests you can find in your area (hamfests = Amateur Radio flea 
markets that usually have all sorts of good stuff cheap if you know what 
you're looking for).
