LL1683: Lundahl Mains Transformer

The LL1683 is a C-core mains transformer with seven secondary windings. The core is assembled with a small air gap to compensate for any mains DC unbalance. The estimated power rating is 120VA, which can be increased with good cooling. The 250V-0V-250V secondaries are internally divided between the two coils. As a result, the transformer can be used with bridge or full wave rectifiers without the problem of asymmetric load. Magnetic stray is tiny if filament secondaries of the two coils are loaded identically.
