AST audio transformers

The best audio transformers in the World?

Our customers think so.

“… who would have believed that merely changing one transformer for another, would create so much improvement in the sound of my Naim 180, my grateful thanks” CT Hull

In the world of transformers, there are many products derived from common or garden industrial units having little or nothing to do with our beloved hobby of high fidelity audio.

Some toroids exhibit such high levels of mechanical noise, it becomes not only audible in the listening environment but the harmonic content of the energy field is interposed onto the musical signal, the regulator systems being incapable of dealing with heavy harmonic saturation.

We supply AST Audio Grade transformers from Advanced Sound Technology, both Toroidal and ‘C’ Cores, ranging from 120VA through 2KVA.

Advanced core material and winding techniques ensure the highest flux density for maximum transients. Probably the lowest impedance secondaries ever made for that extra control in the bass.

Special techniques ensure that HF and RF transmission is minimised meaning a cleaner presentation. Encapsulation in a special epoxy resin guarantees a total absence of noise and vibration (no more audible grunting and a background silence that has to be experienced to be fully appreciated).

Prices begin at £90 for a 350VA AST Transformer
up to £190 for a 1200VA Audio Grade state of the art model
