  for some gain increase the output resistors from 1300 to 2500

for more gain lower the resistance of the 4 emitter resistors, changing the 1k resistors to 500 gives 6 db of gain unbalanced to unbalanced, 12db of gain unbalanced to balanced.

my test layout (before the official one was done)

here Below is Kevin's SMD layout, adapted a bit for my methods
