Like Takeda San when he was OEM for Levinson, Cello, Krell, MoFi and 47Labs before setting up his own Miyabi brand.
47Labs was last destination of Takeda-San, he retired then.
Miyabi was before 47Labs, luckily I managed to get
Standard and MCA models.
JVC Victor may have been a large corporation at the time, but it was not particularly known for phono cartridges.
I think they made millions of MM cartridges (maybe less MC) and Shibata stylus was their patent.
Here is a list of Victor products.
Construction of the
MC1 printed coil is
here.
Construction of MC-L10 coil is
here.
And BTW what Audio-Technica made in 21st century (
ART-1000 ) is just Victor MC-L1000 principle.
"New" is not always new :))
