It would help to know what RH84 is.
The RH84 is an EL84 based amplifier originally designed by Alexandar Kitic... see thread here...
one of many...
ideally the driver should be a pentode and should have a reasonable current capablility. Alex did extensive computer modeling to get the right triode for the job and since its a reasonably cheap tube I wouldn't be inclined to change it.
However if it was me I would redesign for a decent pentode driver such as the 6AU6.
