[QUOTE="Timber_MG, post: 983439, member: 18"] It really depends on the interleaving of the transformer. Most tapped transformers have simple taps on the secondary windings and the highest impedance tap is the best way to go about it in most common hookups. The issue comes at the point where in an A/B amplifier the one valve switches off and you don't want any imbalance in the coupling to the secondary for reasons of ringing and instability, especially with pentode connections' high feed impedance and an odd load on the output side.
