The Amplimo 25PP8K0G is a wide bandwidth toroidal tube output transformer for push-pull amplifier designs, rated at 25 W with an 8 kΩ primary and 0, 4, 8 and 16 Ω secondary taps.
Amplimo 25PP8K0G Wide bandwidth toroidal tube output transformer 25 W 8 kΩ
The Amplimo 25PP8K0G is designed as a toroidal output transformer for tube-based push-pull amplifiers. With a primary impedance of 8000 Ω and a nominal power rating of 25 W, it is built for applications where stable output matching and wide frequency coverage are required.
On the secondary side, the transformer provides 0, 4, 8 and 16 Ω taps, giving you practical speaker-load options in one compact unit. The specified turns ratios are 45 for 4 Ω, 32 for 8 Ω and 22.5 for 16 Ω. Use only one secondary tap at a time.
Performance is supported by a -3 dB frequency bandwidth of 4 Hz to 93 kHz at 1 mW, while the 25 W power bandwidth starts at 50 Hz. Key electrical values include 840 H primary inductance, 8 mH primary leakage inductance, 630 pF primary capacitance and 114 Ω primary DC resistance.
With dimensions of 80 mm outer diameter x 36 mm height and a weight of 630 g, the 25PP8K0G is a compact choice for high-quality tube audio builds and other precision audio components assemblies. Mounting is handled with the included toroidal clamp and washers.
