right.... there is also a 2 ohm tap. But there are also 4 and 8 ohm taps, and it is unlikely that whoever replaced the output transformer used the 2 ohm tap. but perhaps you should check on it.

its basically that transformer.

I'm holding one of those transformers in my hand. So you gotta believe me.

Now that the OT had been identified, you can rewire the speakers in parallel for 4 ohms using the yellow 4 ohm tap. Without a 16 ohm tap for the feedback loop, just connect the feedback to the 8 ohm tap and increase the 15K feedback resistor to 27K. It's all reversible if you decide later to get another OT with a 16 ohm tap. But you can wail on safely for now.
