SINGLE ENDED
TUBE DRIVER TRANSFORMERS
Key Features of Hammond's Single Ended Tube Driver Transformers:
Designed for general purpose or replacement use in single ended or phase inverter tube driver circuits.
Open style with minimum 5" long primary leads.
Minimum frequency response 50 Hz. - 13 Khz. (+/- 1db max. ref. 1 Khz) at full rated power.
Hammond's 124B is the same as their 124A except for the 49% Nickel laminations for greater fidelity.
Hammond's 124C (below) is the COIL ONLY (for those experimenters who want to to use their own "iron").

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. |
