Model 1 Output Transformer (250-0001)
Rated Power: 5W
Primary Impedance: 5k ohm
Secondary (speaker) impedance: 8 ohm
- Height: 1.7"
- Length (measured without mounting ears): 2" (2.8" with the mounting ears)
- Thickness: 1.7",
- Mounting holes are spaced 2.375", hole diameter: 0.175".
This transformer is designed to work with the Basic configuration of the Model 1 Amplifier. You can use this transformer with the Full pack as well and you will notice slight improvement in the bass region, with 10-15% increase in the output power. However, for the maximum power with the Full pack configuration, a transformer with 2.5k primary impedance is required.
BLUE wire: +Va
RED wire: Plate
GREEN wire: Positive output (in phase with input)
BLACK wire: Output Ground
Connections to the Model 1 Amplifier:
Connections are shown on the picture below and they are identical for the left and right channel.
