A470 35W Output Transformer

Antek ST-70 Compatible Output Transformer
Designed as an independent reproduction of the classic Dynaco ST-70 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 ST-70 amplifiers and is also suitable for compatible KT88/6550 push-pull tube amplifier designs.
