I haven’t heard of anyone on the forum using the Classic Tone Output Transformer. It would appear that you use the Blue and Brown on the input side. The output side is fully dependent on the speaker combo and impedance total of those. And on the tube you are using. Check the chart in the book.

It looks like the GRAY on the Classic Tone is the same as the WHITE on the spec’d Hammond 125ESE.
