Some chance the lower impedance tap on the primary is for ultralinear operation. I think I have an old SE Sony tape deck that runs the 6AQ5s in UL. Just a guess though.
Are the transformers big or small? For a small transformer the resistance of the primary seems pretty low. Have you applied voltage to calculate the turns ratio?

Hi, I did no testing other than measuring the DCR. I saw a pic of the stereo amp and it looked like one of those standard type console amps. The opt are not especially small about 2 x 2 1/2 x 2.
