4. Output transformer requirements:
4.1. Basic Configuration: 5k primary impedance, secondary impedance to match your speakers,
40mA min primary current rating, 3W minimum power,
4.2. Full Pack: 2.5k primary impedance, secondary impedance to match your speakers,
80mA primary current rating, 6W minimum power.
Our transformer part number 250-0001 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.
5. Power supply requirements:
5.1. Basic Configuration: Plate: 200 - 250V, 80mA min, Filament: 32V/0.3A (can be reconfigured for 16V/0.6A)
5.2. Full Pack: Plate 200-250V, 160mA min, Filament: 32V/0.6A (can be reconfigured for 16V/1.2A, 64V/0.3A)
6. Power supply PS-1
