Hammond 125B multiple outputs

[Tom Phillips]

this one (from these guys https://www.musicalpowersupplies.com/) is more reasonably priced https://www.ebay.com/itm/16695621999...Bk9SR7aW4ovLZA
I've asked for frequency specs.

The sales text lists "Designed Operating Frequency (+/-1dB): 60 to 15000 Hz" That's good if the actual product meets the Design goal.

Per your diagram, you have shorted the secondary pins #1 to #2. That's critical problem.
It looks like your thinking is to use the switch shown to connect the 16 Ohm jack but the circuit leaves the 8 ohm jack connected all the time.

I'd still recommend that you re-consider using a multi section rotary switch to select your output impedance.
What do you think?

You're right. I need to stop thinking while drinking!
