Yes, but unless it consumes a significant fraction of the load then its
decay time will be rather long.


True, but it's normal. How many bits of valve kit have relay connected
discharge resistors? - almost none. Is there any particular reason why you
need a very short discharge time?


The PSU is remote and the relay has an interlock to turn off the HT if
the PSU HT output lead is disconnected. I need to either disconnect the
HT or bleed it very quickly to avoid a possible shock hazard.
