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

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.
