Hammond Transformers Model 1642SE (1627-1642 Series)
Single Ended Audiophile Tube Output (25-75 W) Transformer - 75 W, 5000 Ohms, 300 ma
This enclosed audio signal transformer is “over-designed” for high-fidelity. These units are designed principally for high impedance triode tubes. They feature high quality laminations, (M6) grain-oriented silicon steel and the core is gapped to reduce core saturation in Class-A tube amplifier circuits.
Features:
- "Over designed" for high fidelity, single ended, Class-A, tube output circuits (triode, tetrode or pentode tubes).
- Enclosed (shielded), four slot, chassis Type "X" mounting.
- Frequency response at least 20 Hz. to 20 Khz. at full rated power (+/- 1 db max., ref. 1 Khz.)
- Insulated flexible leads 8" min.
- This unit is designed principally for high impedance triode tubes.
- High quality laminations, (M6) grain-oriented silicon steel.
- Core is gapped to reduce core saturation in Class-A tube amplifier circuits.
- For general purpose or replacement use in single ended tube output circuits see Hammond 125SE Series.
