Chris, they'll discharge regardless because the rest of the smoothers are effectively in parallel through the inductors - I've never heard of putting resistors in a power supply like this as the end user would not be expected to touch any of it. The valves will discharge the whole lot before they cool after switch off and would only not do so if there were a certain fault condition. From now on, every time someone posts with a vintage valve amplifier, we'd better tell them not to touch anything until they've fitted resistors across the smoothers in case of an unlikely fault.
