Tube Driver - Interstage (124 Series)

Tube Driver - Interstage (124 Series)
TUBE DRIVER - INTERSTAGE
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 150 Hz. - 15 Khz (+/- 1 db max. ref. 1 Khz.) at full rated power.
• Part number 124B is the same as the 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").

• 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.

TUBE DRIVER - INTERSTAGE
TRANSFORMERS
• Designed for driver use ONLY in single ended tube output amplifiers. These units replace coupling capacitor
circuits for improved sound.
• Closed style with minimum 8" long leads.
• All models use bifilar wound windings for exceptional coupling and bandwidth.
• Minimum frequency response 20 Hz. - 20 Khz (+/- 1db max. ref. 1 Khz.).
• The core is gapped to support the specified D.C. bias current.
• Core uses Hi grade silicon laminations (29M6).
• Units weight - 3 lbs. 2 oz.
