LL1669A: Lundahl Mains Transformer
Click to Zoom
LL1669A is a C-core mains transformer. It has 6 secondary windings, a 340V, 0.55A HT plus 4 6.3V, 3.1A valve heater and a 110V, 40mA bias winding. The core is assembled with a small air gap to compensate for any mains imbalance. 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.
Specifications:
- 250VA power rating
- The transformer primaries are connected in series for 210-250Vac and in parallel for 105-125Vac
- Secondary winding 1: 340V, 0.55A
- Secondary winding 2: 6.3V, 3.1A
- Secondary winding 3: 6.3V, 3.1A
- Secondary winding 4: 6.3V, 3.1A
- Secondary winding 5: 6.3V, 3.1A
- Secondary winding 5: 110V, 40mA
- Isolation between windings / between windings and core - 4kV / 4kV
- Dimensions - 118mm x 78mm x 85mm
- Silicon-iron (STANDARD) core material
