We report results of our study of the pressure dependence of Tc in Tl0.2Hg0.8Ba2Ca2Cu3Ox to 6 GPa in a diamond anvil cell. The sample studied has an ambient Tc of 136.4 K and application of quasihydrostatic pressure raised Tc to 144.4 K at 6 GPa. We will also describe recent modifications of our ac susceptibility apparatus that have improved our sensitivity while simplifying the coil design and the balancing.
