So, again, here are the specs for the Classic Tone OT:

Since this OT is limited to either a 5 or 8k primary, and I have it wired up with the 5k primary, I need to figure out which secondary tap/speaker load combination matches the white wire tap on the 125ESE. So, if I use the 4ohm tap on the Classic Tone (yellow wire) with an 8ohm speaker (which is all I have), then a 6L6 tube will think it’s seeing a 16ohm speaker at a 5k primary (how I have the Classic Tone wired), which would be equivalent to using the white wire on the 125ESE with a 16ohm speaker (a correct secondary/speaker match), correct? That’s how I understand how speaker “mismatching” works, but maybe I’m confused…
