RE: 20uF is Not Too High

6X4 data sheets show 10uF as the typical value for a cap-input filter. To determine the actual maximum for a given application, it's necessary to use additional published data. The 6X4 is rated for a maximum transient peak plate current of 1.1A per plate. Charts published by the manufacturer(s) use this peak rating to show the required plate supply resistance in ohms VS the AC RMS voltage per plate, relative to a 10uF cap. Additional capacitance can be used as long as the peak plate current rating isn't exceeded. Simulation software is ideal for determining this.
