The interstage transformer can become your favorite coupling element between the driver and power stage due to its low impedance coupling, faster driver stage overload recovery, high grid current operation and most importantly, its high mass for acoustic dampening with carefully selected materials by Muse Coils. We are currently offering Single-ended or Push-pull1:1 low Rdc interstage transformers. The benefit of 1:1 transformers is the huge variety of driver tubes that can be used due to the good high-frequency performance and primary inductance headroom.
The internals of MinotauR series interstage transformers consist of carefully wound, tight windings, additionally inspected, and packed by hand. The core is HiB with a proprietary modification. Between each winding layer lies a dampening layer of paper. The resulting coils are deeply impregnated within an inhouse high-temperature wax that delivers a fusion of energy, smoothness, and soundstage immersion to the midrange. The mounting elements, all playing a part in the sound reproduction, are made from carefully selected Brazilian hardwood, linked together with brass-alloy rods. Output terminals are not left neglected either, being modified with a mixture of annealed silver and African hardwood.
The interstage transformer can be custom air-gapped on request to be optimized for your favorite set of driver tubes.
