Well, it looks like it is definitely the Filament Choke.  According to this 
calculator I need a lot more turns on the torrid core (FT240-43).  Since it is 
bifilar wound with the 12AWG would you halve the recommended number of turns?  
The third winding is a single winding.  What is your take on 
it?https://miguelvaca.github.io/vk3cpu/toroid.html

This one is how I wound the choke.  Appears it is not keeping the drive out of 
the filament transformer.  Can't get the autotuner I use to tune the input.  
Worked ok 
before.https://coil32.net/online-calculators/ferrite-torroid-calculator.html
Was wondering if I can take the Ameritron bifilar wound filament choke made for 
160-10 meters and wind the 3rd winding on it in-between the existing bifilar 
windings?
Thanks everyone, Bill
