Thanks for sharing your experience. I'll try running it with the shield removed and see if there is a purple glow in the gun.
One last bit of business. The original speaker cone is trashed.
I looked through some other sets and came up with these other two.
All three appear to have the same 78B40 part # in spite of the difference in frame and magnet size.
I suppose it doesn't matter as long as the mounting holes line up and the wattage/impedance matches.
