A number of people have been experienting with the use of Microwave 
transformers to power Tesla coils. You can put them in series 
(actualy you put the primaries in parallel and the secondaries in 
series) you must disconnect the side of the secondary that is 
grounded to the core. and add some insulation to the lead and it is 
wise to imerse all the transformers in oil to increase their voltage 
tollerance. To current limit them you can use a series choke either 
fixed or tapped or one with a sliding iron core to vary the
