RE: Testing without a Coil: Dummy Load?

Replacing the secondary with a dummy load would be difficult - resistors 
with such a voltage rating are not trivial.  But I have had good results 
with replacing the primary coil with a dummy load to permit spark gap 
experiments.  I was using a 15/60 NST power supply, and I replaced the 
primary coil with 3 or 4 500W 120V halogen tube-style lamps, in 
series.  See photo at http://www.laushaus-dot-com/tesla/sync_gap.htm.  I think 
as long as the wattage is in the ball park with what your NST puts out, 
they should work nicely.

Hi All

Recent posts about a firey spark gap on a coil-less coil begs the question:

Can we hook up a dummy load rather than a secondary, as we can with a
transmitter?  If so, what form would this load take?

Cheers
