My secondary is also 6" diameter 28"long. Running two 12kv 30ma nst's phased with a double static gap and the same type of caps but mine are 2 strings of 16 (32total) vs your 72? I get 3-4' streamers. Should I be using more caps in my mmc?

My math could be wrong (and usually it is) but that tells me youre running
89 breaks per second?
You should be running 5 - 6 times that.
Im also assuming this is not a synchronous motor.
A SRSG with a phase angle adjuster would be the way to go.
Also, from the photo it looks to be a little under coupled but I think your
main problem is the low break rate of the gap.
