        LL1623-120 Output Transformer for Tube Amplifiers 120mA

        Product description Lundahl LL1623-120 Output Transformer

        The Lundahl LL1623-120 is an open-frame output transformer for tube amplifiers, built with a gapped audio C-core for 120 mA operation and a highly sectioned winding structure for wide-band performance.

         

        Highlights of the Lundahl LL1623-120

        • Output transformer for tube amplifiers with 120 mA DC current rating
        • Special Lundahl audio C-core, gapped for the desired DC current
        • Highly sectioned, harmonically sized windings for very low leakage inductance
        • Low-capacitance winding technique for wide frequency range
        • Flexible secondary connections for 4, 8, or 16 ohm loads
        • 3 kV primary-to-secondary isolation and 1.5 kV winding-to-core isolation

         

        Product details Lundahl LL1623-120

        Lundahl LL1623-120 Output Transformer for Tube Amplifiers 120 mA

         

        The Lundahl LL1623-120 is designed for tube amplifiers and belongs to Lundahl’s LL1623 output transformer family. It uses the same core size, winding structure and secondary layout as the related LL1620, LL1627 and LL9202 models, with primary turns selected for the LL1623 impedance level.

         

        Its highly sectioned winding structure with harmonically sized sections minimizes leakage inductance, while the low-capacitance coil winding technique supports a wide frequency range. The LL1623 design has a 4 x 13.4 : 8 x 1 turns ratio, 164 ohm primary DC resistance with all primaries in series, 0.4 ohm average secondary resistance and 4.6 mH primary leakage inductance.

         

        For the 120 mA single-ended version, the LL1623 offers a 23 H primary inductance operating point. Primary load impedance options include 5.6 kOhm, 3.0 kOhm and 1.6 kOhm depending on the chosen secondary connection alternative, making it suitable for a range of tube output stage designs and load matching requirements.

         

        The open-frame construction is intended for mounting inside an amplifier housing. Practical installation details include a 5.08 mm pin spacing module, 4 x M4 mounting holes and a 2.5 kg transformer weight. As a high-quality choice among specialist audio components, the LL1623-120 provides flexible secondary wiring for 4, 8 or 16 ohm speaker loads.
