A431 60W Output Transformer

Antek Mark III-Compatible Output Transformer
Designed as an independent reproduction of the classic Dynaco Mark III output transformer, this EI-core transformer is engineered to deliver the performance characteristics associated with the original design.
Manufactured using high-quality silicon steel laminations and carefully wound coils, it offers excellent frequency response, reliable power handling, and low distortion. It is an ideal replacement for Dynaco Mark III amplifiers and is also suitable for compatible KT88/6550 push-pull tube amplifier designs.
