This cartridge with this stylus is very problematic.
The stylus is used, condition unknown, so we don't know if this is how these styluses are manufactured, or if this copy is, perhaps, in poor condition.
However, this is not the first case that buyers have reported problems after purchasing a stylus from Jico for this model.
Below are the measurements of this set published elsewhere.
As you can see, MI inserts are insensitive to the charging capacity, or at least it is not a critical parameter.
By the way, I don't know why this particular old series, from the mid-70s, is more popular than the newer series, EDR9, 600LAC, Empire 1080 cartridges, etc.
Ps: The creator of the script for measuring the frequency response of a turntable cartridge should be carried in a sedan chair like a Pharaoh.
