Default One for the valvies 1/2....

Well yeah and I wish my valve amp, and others, had multifilar
secondaries, so you could choose, for example, whether to
connect 2 4-ohm secondaries in series for 8 ohms, or in
parallel for 2 ohms with less voltage but a lower o/p impedance.

As a rule of thumb, the greater the turns ratio the more inefficient a
transformer becomes.
