TRON Nemesis

Nemesis Preamplifier

Once in a lifetime something really special comes along which changes people perception of what is possible in terms of performance and quality. Two years in the making, enter the Nemesis! A valve preamplifier all others will be judged against.

Control Unit
It took 5 years to locate all the parts to build this very special preamplifier and a further 2 years to design and construct it.

The Nemesis is a two-box preamplifier, one box houses the power supply and the other houses the audio circuit. There is only one triode in each channel and the output is coupled to the power amplifier by a very special hand wound output transformer of the highest quality and using an extremely rare C-core design with an exotic core. These are custom made and therefore not available to anyone else. There are no capacitors or resistors in the signal path in this amplifier.

A very special 42 position stepped attenuator is used followed by the amplifying triode then the output transformer so this is the nearest you get to “wire with gain”. All internal wiring is made from audio grade 5 nines pure silver. All RCA sockets are the top quality WBT pure silver types.

The power supply is also very special and houses 4 separate mains transformers. Chokes are also used along with very rare capacitors.
