- 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 (+/- 1db max. ref. 1 Khz.) at full rated power.
- Part number 124B is the same as our 124A except for 49% Nickel laminations for greater fidelity.
- Part number 124C is the COIL ONLY (for those experimenters who want to use their own "iron").
Hook Up 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 centre tap) - GRN/YEL and BLK wires are the output.
