Approx. 5 min straight run time is the longest I have ever run my coil. My
coil uses dual MOTs with no voltage doublers or safety protection, a 110nf
18kvdc MMC, and a 460 BPS Async rotary, and kicks out 6+ feet of spark.
Really the only thing that limited my coils run times before I switched to
the rotary (yes its the all metal rotor, directly on the motor shaft rotary
from several months back), was the 15A breaker I run on (max of 1 1/2 min
w/ the airblast gap), but now I can run my coil for about as long as I want
to with no problems.
