Three different types of non-rfq resonators 1 are included in the PIAVE 2 low beta linac under construction at LNL, i.e. 8 superconducting, β=0.047 quarter wave cavities, a room temperature β=0.0089 triple harmonic buncher and two, β=0.05 room temperature quarter wave rebunchers. The construction and testing of the superconducting cavities has been successfully completed, the design goal of 5 MV/m at 7 W was more than fulfilled with a measured average gradient of 6.7 MV/m; the triple harmonic buncher was successfully tested and installed in the beam line; the 10 kW, high energy rebunchers are under construction and their completion is expected within 2000. The installation is proceeding according to the PIAVE schedule. 1 THE SUPERCONDUCTING LOW-β
