An old Sansui Amp with no dates on ICs, Transformer, caps, trannies etc.
Two plastic end pieces marked Sanyo, one Left & one Right hand.
Both have 82 83 84 85 with a small moulded pip over both 82 and 83
Then a 1 to 12 'clock face' both with an arrow next the figure 8.
Also in the centre of these dials is in one case a small raised
diametric bar pointing between about 7.6 and 1.6
and on the other bar moulding about 3.8 to 9.8.
Can anyone decode mainly the 1982/3?

Does this seem likely - a centre pop dimple in the mould above
82 in 1982 and then another over 83 in 1983. Leading to
raised small conical pips on the plastic.


It sounds like the mold was first used in 1982, and still in use in
1983. they just drill a dimple in the mold every time it increments
rather than changing a stamped plate on the mold, like the early days
when you saw the screw heads and outlines of the plates.
