Tube Driver - Interstage · 124 Series

Brand: Hammond Manufacturing · 6 part numbers

■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").

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.

■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.

■Connect the BLK/YEL wire to the GRN (this becomes the center tap) - GRN/YEL and BLK wires are the output.
