later of ZYX fame.
I am aware that before Zyx he worked for Monster Cable with the Alpha and Genesis series ... I do not remember if it is always the same designer of the Ortofon Mc 20 30 etc. etc.
The original MC30 was also a very low output device at 0.1mV (my sample is even lower at 0,09mV)
also my two MC 30s ... one 0.09 the other 0.092/0,093mV but I knew an owner that the output was 0.085mV.
