Thanks again Tan! So the input impedance should be 5Kohm then right, if I’m using the blue and brown leads? The secondary looks like it’s just a matter of matching the speaker impedance. In my case, I’m using a 6V6 output tube and 5Kohm primary impedance on the OT, and an 8ohm speaker. So the I should use the black and green secondary wires for the output jack, correct? Here’s a link to the Classic Tone spec sheet:


I really appreciate your help!
