Amplimo 10PP9K0S Wide bandwidth toroidal tube output transformer 10 W 9 kΩ

The Amplimo 10PP9K0S is designed as a toroidal output transformer for push-pull tube amplifiers. As part of a high-quality audio components build, it matches a 9000 Ω primary to selectable 0, 4 and 8 Ω secondary connections.

With a nominal power rating of 10 W and a -3 dB frequency bandwidth of 4 Hz to 80 kHz, the 10PP9K0S is built for wideband tube amplifier performance. The power bandwidth starts at 35 Hz, supporting stable low-frequency operation within its rated range.

The primary side includes 35% UL taps for ultra-linear configurations, with a turns ratio of 47.3 for 4 Ω and 33.9 for 8 Ω. Electrical specifications include 750 H primary inductance, 52 mH primary leakage inductance and 335 pF primary capacitance.

The transformer measures 83 mm in outer diameter and 37 mm in height, making it a compact toroidal solution for amplifier chassis integration. It is supplied for mounting with a toroidal clamp and washers. Use only one secondary tap at a time.
