I measured one of those transformers with a signal generator. Looks like the aux tap was about a 2 ohm tap. Would make sense... that would make the aux speaker a little less loud than the main. Or, if you wanted to wire BOTH the main and aux speaker to one tap... it would work.

I know this is an old thread but currently I am trying to sort out how I can use these two taps for running the speakers in my signature. If the output transformer has two taps than can I use the 2 ohm section for a pair of 15" Magnavox woofers and the 4 ohm section for the treble horns? Does the speaker selector switch on this amp do 4 ohm and 2 ohm simultaneously or does it see the 2ohms by paralleling the internal and external speakers? The woofers are 4 ohms but I run them to a subwoofer that highpasses them at 80hz. The rp 109horns are 12 or 16 ohms and the foster is 8 ohms. I guess I don't understand the way the speaker selector switch is using the amp and if I would be overtaxing it. Thanks for any help!
