Could it still be a typo but maybe it was meant to say 1500 mV instead of 51 mV?
It would make more sense for it to of been a typo and for them to of meant to type 1500 mV (1.5 V, which is what some of your ceramic and later crystal cartridges put out voltage wise) with the number 51 because with Japanese being read and written right to left instead of left to right like English is, the person who typed up the schematic might of accidentally tried typing in Japanese rather than in English reading style and forgot to correct it (hence 51 which would read as 15 in Japanese.)

Or going down that same typo rabbit hole perhaps it was meant to say 1.5 V rather than 51 mV (again same concept as the previous point except that they forgot the decimal, inverted the 5 and the 1 (rather than 1.5 they put 51 because they accidentally reverted back to typing in Japanese style of reading, or was just typing too fast and didn't pay attention to what they were typing and accidentally put the "m" in front of the V, when it was supposed o be just a "V". )

I'm asking because the known line level inputs like the AUXilary input and the Tape Monitor inputs (which are line level inputs) are marked 200 mV on the schematic.
