The Amplimo 50PP4K0G is a wide bandwidth toroidal tube output transformer for push-pull amplifier builds, offering a 4 kΩ primary, 4 Ω, 8 Ω and 16 Ω secondary taps, and 50 W nominal power handling.
Amplimo 50PP4K0G Wide bandwidth toroidal tube output transformer.
The 50PP4K0G is designed for tube amplifier applications where a push-pull output transformer with a 4 kΩ primary is required. Its toroidal construction makes it a focused choice among specialist audio components for valve-based output stages.
With a frequency bandwidth of 8 Hz to 167 kHz at 1 mW and a power bandwidth starting at 50 Hz at 50 W, this transformer is built for wideband audio performance. Key electrical values include 465 H primary inductance, 3 mH primary leakage inductance, 530 pF primary capacitance and 49 Ω primary DC resistance.
The secondary side provides 0, 4 Ω, 8 Ω and 16 Ω connections, giving flexibility for common loudspeaker impedances. Use only one secondary tap at a time to ensure correct operation and loading.
The transformer measures 91 mm in outside diameter and 44 mm in height, with a weight of 1.0 kg. Installation is supported by toroidal clamp and washer mounting hardware, making it suitable for clean integration into custom amplifier chassis designs.
