Linn Sondek LP12


Recommended Posts

I have a Linn LP12 ( maybe late 80s model). Just installed a replacement circuit and now runs well.

Does anyone know what is missing re the hole under tone arm. Should there be a stabilising arm in this spot?

Not sure what to search for!

Look at the back of your deck for the serial number and if it's not there then lift the platter and peek under there.

Looks like a 70's model to me unless its been Nivaned/Vahallad.

Simple fix is to look up the serial number.

Good TT.
What model is the Grace Tonearm?

Your tonearm is either a Grace 727 or 747( my eyesight is not what it used to be)and from your pic, you are missing the anti skate weight (shared by 707,747 and 840 as far as I know)
