Good move.
This incident will get me being super-careful when I lift and drop the arm onto the deck. No cueing device, so it can be very 'hit and miss'.
That was the problem: I trusted the cueing lever, that for unknown reason was down. (actually the reason is probably that I didn't place the lever at the very end when I lifted the tonearm, so the weight of the cartridge moved it down.) When I had the Linn, no cueing on tonearm, therefore I was super-careful.
