‘Every solder joint is one too many’. This simple wisdom was our stipulation for the internal wiring of the SUT-1L. For the two transformer stages – 24 dB and 30 dB voltage boost – two separate inputs are used, to which the signal lines of the transformer are directly connected. There is no need for another switch.
This enabled us to reduce the number of connection points by 70 %. For the remaining wiring paths, we used specially manufactured and individually twisted strands. In this way, we again minimised the negative influences on this short, but critically sensitive, signal path. No resonance-prone circuit board was used, which drastically reduced the construction time, nor were mutually influencing signal conductors: instead, self-sufficient, individually shielded signal conductors with capacity reduced by 60 % were used.
