hey Greg..

If your coil is putting out streamers comparable to other coils of the 
size and power, its quenching  :)
Attempting to put an O-scope on a primary ( or even near a primary) 
could lead to the death of the scope...

hi voltage from the supply itself, EMP EMF from the primary, inductive 
voltages etc... are things to consider
O-Scopes, even tho most are shielded, can be influenced by exterior 
sources. Mine can give erratic readings if I have a flourecent lite too 
close to it.

See what other people have to say about protecting a scope in that 
situation.... Ive never done it due to the fear of trashing mine...
