Valve Amplifier Output Transformers

Valve amplifier output transformers — also known as tube amplifier output transformers in the US — are a critical component in any high-quality amplifier design. They provide the impedance matching between the output stage and your loudspeakers, shaping both power delivery and tonal character. This collection brings together a range of premium output transformers suitable for DIY builders, repair projects, and custom hi-fi amplifier designs. Whether you’re building a push-pull EL84 amp, a single-ended triode design, or upgrading an existing tube amplifier, these transformers offer the performance, reliability, and musicality that great valve amps are known for.
