SAEC 308N vs 308SX

Dear Lew, I own the SEAC 407/23 for which it seems to be impossible to get the u. manual. So I made a copy of 308N from VE to get some idea about the construction. There is no mention of null points in this manual. For my 407/23
there are also all kinds of 'suggestions' reg. the null points but nobody knows for sure. According to some former Australian importer of the SEAC brand the sufix '23' means Baerwald but this was dismissed by others as a myth. It is
very strange that there are so many indistinc opinions about SEAC geometry.BTW I assume that you know that there are two versions of the 308; the sufix 'N' refers to 'new'.

Geoch, yes Allen Wright is the person I refered to as 'the
Australian importer' who induced SEAC to produce 407/23.
He thought that this way SEAC would be more acceptable for
the Western customers who were more familar with the Bearwald geometry. This guy seems to be many-sided talent but I am not the right person to write about him.

Dear Lew, This is a quote about SEAC WE-308 SX from 'Tonearm Geometry and Setup' (Kessler&Pisha,Audio,January 1980): 'The SEAK WE-308 SX arm design is based upon research done by the Sansui Electric Co. The AES preprint 1390 (D-5) derived the optimum pivot position from a kinematic point of view,with
the mass of the arm ,the location of the center of gravity,
and the moment of inertia around the system's center of
gravity. Resonance was the engineering problem being solved. For this prticular arm ,it is not advised to optimize the geometry, or the resonance of the system will
change to such an extent that the arm will not track properly.'
So obviously this arm is not only unique qua price . BTW you should know that reaserch is very expesive and need to be earned back somehow. I assume that 308, 308N, 308 L and my 407/23 are not 'inflicted' with the Sansui research and
that te owners of those arms may 'mess' with different geometries? There is no other choice btw because SAEC is very confusing or not very clear about,say, the null points.

Dear Daniel, What kind of German are you? I thought, because of Wagner, that you are very fond of all kinds of mythology. Do you really need to destroy the SEAC kind?
Never in my life I was so dependant from a sufix. Ie I hope
that my 407/23 and more in particular the sufix '23' is something 'totally different' in the SEAC brand (aka the Bearwald geometry). You should postpone your answer till I
sell the thing(please!).

Dear Lew, 'Dear Nicola or anyone else' is not to the liking
of my 'super ego'. I am alas not an expert in kinematics, have, to be honest, no idea what 'kinematics' means so you are overating me in one aspect of the issue while underating me in some other. My idea is that you should design some
other tonearm base for your second arm on your beloved Kenwood.Ie this SEAC enigma is developing from bad to worst.

Dear Lew, This '23 offset angle' by SEAC 407/23 was exactly the story of the Australian importer of the SEAC brand who seems to be at present an succesful designer of HIFI gear Switzerland. If you persist I will search for his name. But Daniel scared me (nearly) to dead with his Kantian way of judgments. I am probable more sensitive to
German threatening than you are. But you are even messing with those 'transfomerless amps' which seems to need at least 1000 spare tubes. Is there any space in your cellar
for some wine btw?
