        LL2735B Output Transformer for Tube Amplifiers 30mA

        Product description Lundahl LL2735B Output Transformer

        The Lundahl LL2735B is a 30 mA tube amplifier output transformer with a 16k:8 ohms impedance ratio, designed for single-ended applications with high-rp tubes such as 10Y, 801A and EML20B.

         

        Highlights of the Lundahl LL2735B

        • 16k:8 ohms impedance ratio for single-ended tube amplifier output stages
        • Designed for high-rp tubes such as 10Y, 801A and EML20B
        • Dual-coil construction with high internal isolation and isolation foil between copper layers
        • Silicon-iron audio C-core produced by Lundahl
        • 90 H primary inductance with 300 V rms maximum primary signal at 30 Hz
        • 5 W maximum output power at 30 Hz into an 8-ohm loudspeaker load

         

        Product details Lundahl LL2735B

        Lundahl LL2735B Output Transformer for Tube Amplifiers 16k:8 Ohms 30 mA

         

        The Lundahl LL2735B is built for demanding single-ended tube amplifiers where a 16k:8 ohms output transformer is required. Its 23 + 23:1 turns ratio makes it suitable for matching high plate-resistance tubes to an 8-ohm loudspeaker load, with suggested use including 10Y, 801A and EML20B tubes.

         

        Internally, the transformer uses a dual-coil design. Each coil contains one primary and two secondary sections, wound with Lundahl’s high internal isolation technique. Isolation foil is placed between each layer of copper wire, while the isolation between primary and secondary sections increases progressively toward the tube anode connection to help minimize capacitive energy storage.

         

        The LL2735B uses a silicon-iron audio C-core and is specified with a primary inductance of 90 H. It supports a maximum primary signal of 300 V rms at 30 Hz and delivers up to 5 W at 30 Hz into an 8-ohm loudspeaker impedance, making it a focused choice for specialist tube amplifier audio components and output stage builds.

         

        Practical specifications include a weight of 1.35 kg, 270 Ω static resistance for each primary and 0.2 Ω static resistance for the secondary. The transformer provides 4 kV isolation between windings and 2 kV isolation between windings and core, with a maximum DC current of 100 mA through any primary winding.
