Anyone come across a tonearm with a single pivot point rather than the
normal four pivot gimbal ? I have a Thorens TD160 Mk II on the bench
that has come in to have the owner's 'soldered with a hot poker'
cartridge connections corrected. It appears not to be the original
tonearm that's fitted, which was a standard fully mounted type
according to the user and service manuals. This arm is a slim black
skeleton, and it just seems to rest on a single spike sticking up from
the mounting plate. If it wasn't for the wires, you'd be able to lift
it right off the deck. There is a fishing line-hung LBC weight on the
left, and the tracking counterbalance weight, as well as being
adjustable fore and aft to set the tracking force, is also mounted
eccentrically, so that it can be rotated to negate any off-axis force,
such as from the LBC weight, which would try to rotate the arm about
its long axis.

I have never seen a single bearing arm like this before, and it doesn't
have any name on it at all. Anyone know what it is ?

Can't help with the arm, but weren't Thorens decks available on their own
so you could bit the arm of your choice? My 150 was - it's got an SME.
