There are different ways to judge about ''sense and nonsense'' of
whatever advice in this forum. All will assume some criterion.
My will be counting while the involved advice is to not solder
the coil wire becausse of (destructive?) influence of ''soldering
points'' on the ''pureness'' of the (thiny) signal.
We have first 4 coil wire which need to be soldered on the 4
cart connectors. Then the cart need to be connected with 8
soldered clips on the headshell wire (=12). The headshell
than need to be connected with 4 soldered connectors on
the tonearm wire at the front side and then those 4 wire need
to be solded to the (female) Din 5 connector at the opposite
side (=20). Then we have the phono-cable with (male)
Din 5 connector on one side and, say, two RCA connectors
on the other side(=28). We should not count the ground wire
nor the soldered input connectors on the amp .side.
However the expert from Mexico forget to mention where his
advice to get new coils for the Miyabi can be ordered.
