So far as I know HT wise the UU5 should be ok but heater wise it needs 2 amps or so, if the PSU originally had a DW2 or an 1821 fitted then note that the heater current for those is shown as 1 amp in the data books, I would hate for your transformer to get hot, see what the others think just in case I've got it wrong.
