Hello Petter, the easiest way is to use Wireline to create two (one for
input, one for output) 180 degree phase shift transformers.
This is what is done in the DEMI 1296 amplifiers. the links below are
for the 60W and 120W 1296 amplifiers using this principal.
I have made these transformers with excellent results.

Here is a link to SAGE cable were you can purchase the wireline needed
to make the phase shift transformers.
