+1 on Morzh's comments. I speak from experience. No load voltage could exceed 500V. Was working on an Arvin Rythm Baby chassis and was measuring B+ voltage with no speaker (and no B+ to output tube screen grid, another thing to ensure if there is no voltage on the plate). I measured 550V just before the input filter cap blew up.
