EDIT: Output Transformer

In my last post I mentioned drilling the chassis in order to place an impedance switch in the circuit.

I could skip the switch and wire either the white or the yellow wire directly to the input jack. If I did this I would only get the following:

White wire: one 6L6 = 8ohms speaker
Yellow wire: one 6V6 = 8ohms
one 6L6 = 4ohms

There is also an optional green wire that you can read about in the book.
