Hi Terry, Adam,

To re-enforce what Terry's saying, I run a 10 kVA pole pig powered 
Tesla system at up to around 8 kVA for up to 3 or 4 minutes at a
time with ALL BRASS electrodes, both the stationary and the ro-
tory flying electrodes. There is slight electrode corosion over time
of the flying 3/8" dia. X 2" long threaded brass electrodes but since 
the system is already fully assembled and it does work, I'm not go-
ing to "fix it" by changing over to tungsten electrodes, at least not 
at this particular time. The stationary electrodes (4) are 1/2" dia. X 4"
long threaded brass electrodes, each affixed with 4 aluminum heat 
sink fins. 

Coiling in Memphis,
