  The high intensity proton accelerator facility at PSI is capable of providing beam currents of up to 2.4 mA at a kinetic energy of 590 MeV. PSI is following an upgrade plan to further increase the beam power and to further minimize proton losses. Up to now, this has mainly been achieved by the installation of high gradient copper resonators in the Ring cyclotron and the installation of more powerful RF-amplifiers. Currently, PSI follows a similar approach for the Injector 2 cyclotron providing 72 MeV protons for the injection into the 590 MeV Ring cyclotron. In order to increase the turn separation in the injector cyclotron which results in lower relative beam losses, the two 150 MHz resonators operated in accelerating mode are replaced with two 50 MHz Aluminum resonators providing higher acceleration voltage. This paper describes the status of the upgrade, i.e., the replacement of the first resonator and related hardware.
