Hammond Transformers Model 124C (124 Series)
Tube Driver - Interstage - 5 W, 10 kOhms, 403 Ohms, 90 kOhms C.T., 1524 Ohms
This open-style audio signal power transformer is designed for general purpose or replacement use (not Hi-Fi), in push-pull or phase inverter tube driver circuits. This version has no laminations - it is the COIL ONLY (for those experimenters who want to use their own "iron").
Features:
- Designed for general purpose or replacement use in push-pull or phase inverter tube driver circuits.
- Should not be used for single ended applications. They have no gap for DC bias current present in SE mode.
- Open style with minimum 5" long primary leads.
- Minimum frequency response 150 Hz. - 15 kHz (+1 /- 3db) @1 kHz.
- This model (C) is the COIL ONLY (for those experimenters who want to use their own "iron").

Hookup Data:
For Parallel connected operation (33.8K Ohm Secondary): Connect the GRN/YEL wire to the GRN wire AND the BLK/YEL wire to the BLK wire.
For Series connected operation (135K Ohm Secondary): Connect the BLK/YEL wire to the GRN (this becomes the center tap) - GRN/YEL and BLK wires are the output.
