LL2740: Lundahl Mains Transformer

The LL2740 is a C-core mains transformer made up of 4 secondary windings. The core is assembled with a small air gap to compensate for any mains DC unbalance—the estimated power rating is 250VA, which can be increased with good cooling. Magnetic stray is tiny if the secondaries of the two coils are loaded identically.
