Hi, I saw this kind of protection on DFS-V system at 1990s, I didnt understand at first time why they put diodes and zener front the input pre-amp. DFS-V is seismic signal acqusition systems and it was developed by Texas Instruments in 1980s. There were also conductance in series at both inputs of pre-amp . I wonder the case system not power on? Thank you very much Art. It is very informative post. Regards.
