Timestep have announced a new tonearm at the Bristol Show which Ammonite Audio will be offering shortly. Some people might recognise the heritage of this arm, but it is an OEM design manufactured for Timestep and available in 9", 10" and 12" lengths, all with Jelco mounting pattern and the same overall geometry as Jelco arms of the same lengths.
