The Varilift also used a thick viscose liquid for a smooth and dampened up and down movement of the tonearm.But now we come to the final phase of the record, the end groove. As somebody once put it “the endgroove is definitely not the right place for the needle to be” , and very much correct due to excessive wear.
Full automatic turntables had an automatic return function when reaching the end groove, but this was determined undesirable on high-end decks as it required a vulnerable mechanism that moved the tone-arm in a very abrupt way.
So, what now to do to prevent the needle running endlessly in the end-groove when you’ve either fallen asleep while listening to your favorite tracks, or left your sound system unattended ?
Around 1969 Colton came up with a solution for this problem in the form of the Magnalift, at that time with a pretty large black base, later in the Mk II version with a smaller satin chrome base. As the name implies, it works on the principle of magnetism. The arm is positioned in such a way that when the tone-arm reaches the end-groove a tiny little magnet that is affixed near the shell on the tone-arm comes close enough near the magnet of the Magnalift, so that the tone-arm is lifted and the needle of the record.
