Version 1.32
Connect a wire from terminal B4 on the output transformers (this is the 8 ohm tap) , to
points X11 on the corresponding PCBs for the negative feedback connection. It is a
good idea to wire the right PCB first as this is further away and the wire will be
longer. Now cut the wire for the left PCB to the same length as the right to give the
same feedback path for each channel.
Configuring The Output Transformer For PP Mode:
Output transformer for Edison 60 power amplifier kits. Top view down with pins
closest to you. PLEASE NOTE : New transformers have slightly different end frames
so may need 2 extra holes drilling in the chassis to fit them properly!

PLEASE NOTE - NEW TRANSFORMERS NO LONGER HAVE POSITION
B2 – 2 OHM TAP – ONLY B4 = 8 OHM AND B3 = 4 OHM
