Well,
I could almost bet on it also but I am still puzzled.
Her's the sch again.
The coil that burned is the one paralleling C6.
When you buzz across C6 it is open.
Now, the coil in series with it conducts. I am not sure whether it was burning or not, the color is dark on all coils. Maybe because one of them is surface and another one is a thicker winding, the thicker took the brunt.
But if you look at the sch, the cap in series with the antenna is 2nF. This at 60Hz is about 1.3 Mohm, or 90 uA of current which is not capable of hurting a dang butterfly. And the cap is 600V.
So I am still not sure what happened.
The only thing is, the coil is burned and the power cord was bare wires which to me also indicates it burned. Which is also strange as the cord can take about 20A before it starts smoking in about 10 seconds or so, and the coil should evaporate should it see that kind of current.
Does not really click.....
