This is worth restating for first-time amp builders: Check the break-down
voltage rating of the resistors you plan to use for bleeders. Most resistors
capable of dissipating the wattage will withstand 400 V, but read the
datasheets. Surplus components with unknown specs are a big risk. You
definitely want some headroom for components that get hot, and that are
installed in a confined space. A HVPS is not the place to cut corners.
