3. Each output transformer has 2 8-Ohm windings. In this version of the amp, both windings are terminated with binding posts. These can be paralleled for 4-Ohm speakers or series'd for 16-Ohm speakers or for speakers for which one wants less damping.That don't sound right.
If you have two 8 ohm windings, and you parallel them, you end up with one 8 ohm winding. The number of turns doesn't change. If you wire them in series, the turns doubles and you end up with one 32 ohm winding.
