Hammond Manufacturing Company Inc. Transformers - Audio Transformers - Tube/Valve Audio 124A

Description
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. Our part number 124B is the same as our 124A except for 49% Nickel laminations for greater fidelity. Our part number 124C (below) is the COIL ONLY (for those experimenters who want to use their own "iron"). If you are looking to replace Radiola III-A audio transformers, check out our universal radiola replacement unit. 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.
