| cpi || 4cM500,000g cpi 4cW50,000J 4cM500,000g The 4CM500,000G is a ceramic/metal, multiphase cooled (water/vapor) power tetrode designed to be useed as an exact replacement for the Thomson TH-558. This tube has a thoriated tungsten mesh filament and pyrolytic graphite grids which provide high dissipation combined with low secondary emission characteristics. Base coaxial contact rings are provided for the filament, grid, and screen terminals. These are forced air cooled. Maximum anode dissipation is 500 kW steady state with multiphase cooling. chaRacteRistics Plate Dissipation (Max.) Screen Dissipation (Max.) Grid Dissipation (Max.)
