Yep, the only valid test of a HV rectifier is how well it performs in a working set. A damper may apprear to perform OK, but abruptly arc heater-to-cathode when you tap it (that's the best test for a damper tube). A horz.output tube may be slow to fill out the screen at turn-on. Yet a tube tester may show a tube 'good' in each case.
