Lundahl Silver wire Amorphous Core Tube amplifier output transformer, LL2752AgAM

Silver wire Amorphous Core Tube Amplifier Output Transformer LL2752AgAM

LL2752 is an output transformer for tube amplifiers, primarily designed for 2k : 8 ohm applications. The LL2752 is available with different core air-gaps for different type of output stages. The transformers are highly sectioned with harmonically sized sections, which results in a minimum leakage inductance. This combined with a low capacitance coil winding technique results in a wide frequency range. The transformers are un-potted, open frame type suitable for mounting inside amplifier housings.
