When you do the twinax, which side might matter as the balance trimmer
affects only one side relative to ground.  I haven't yet tried to 
optimize the
input with this trimmer - I followed the balance method with two resistors
aiming for a null as in the book but single sided input might be better
adjusted. Any thoughts?

Cheers, Gord (VE3EOS)
