I decided to take a skew view before wiring in
http://home.graffiti.net/diverse:gra...et/ful-fi4.jpg
2 rings of green silicone rubber sleeving to take silvered wires before dabs
of gummy glue.
One black rubber pad chamfered to rest in the top cover, yellow-white rubber
pad cut down , orginal brown rubbery moulding that enclosed both original
rochelle crystals and extensions to both stylii saddles.
The saphire of the original remounted ( coded yellow and green) stylus is
just visible to the top and right of the brown section, through a gap in the
white plastic casing.
The original small plastic stylus saddle went quite neatly through the hole
for the original rochelle.
The now unused second brass screw mount for the other stylus and its
corresponding saddle rest flat, on the brown section, is visible on the
lower edge.
Decided to wire in only one active element of the Sonotone and also to have
more space to play with ditch the 78 option and just use 2 of the original 3
pins and plates to the outside. It is very critical on signal generation on
how much the rubber supports are compressed, I may cut the thickness down a
bit if the sound is ropey.
It would probably be possible, in space terms, to separate the 2 sonotone
and mount one either side and retain double stylus, rotating function.
