first tie pins 6 and 7 together and this will become the grounded center tap.feed a signal from your voltage amp to pins 1 and 6. Pin six is grounded and pin 1 goes also to the grid of a tube.
next is that pin 8 goes to the grid of the other tube....
so pins six and seven are at ground and form the CT. And you feed pins one and six as your "primary"... and you derive an equal voltage output but of opposite phase btwn the CT and pin 8 (which feeds other grid)...
is this clear?
and remember that you can only put a max of 6.15 volts across pins 1 and 6. So the grids your driving must be say approx -8 volts or less.
