I ran my twin set up, that does not have the small toroid, and the Al gets 
warm.  It happened on both coils, and only in the center where whe wire 
connects.  By the way, im getting pretty nice streamers now.  Heres an 
interesting topic, Do dischage points have a conciderable effect on tuning?? 
  With out a breakout point on each coil, they have thick arcs reaching 20" 
or so between coils, then if i try to put some thread rod as a break out 
point, the streamers become weak little 8 inchers.  I havent had time to 
play with this yet, i will try to retune with the breakout points, and the 
tuning is really sensitive with the larger cap. Unfortunately, my coils tune 
at 3.5 turns with my large cap, and the small setup i have.  I think that i 
will make some more toroids and lower my frequency.
