BRETT: "I found these 512s to have plastic bobbins that fit over the
centre blade of the pickup. They are wound counter clockwise (anti clockwise) with 43 gauge wire.
The coil's inner wind was attached to a fine insulated wire and routed through a small hole in the bobbin.
This fine insulated wire was then attached to the frames ground point .
The outer wind of the pickup was attached to a fine insulated wire and soldered to the output lead. The braided shield
of the pickups lead is attached to the frame's ground."
Bobbin with pole screws.
Frame and bobbin, a bit out of focus but it shows the pole-piece holes.
The two magnets are lying flat on each side of the centre "blade". By
the way, the magnets are ceramic, not cast alnico as was used on all previous
Bobbin end showing magnet arrangement and
screw pole-pieces on right-hand side. The two horizontal magnets can be clearly
seen under the coil bobbin.
