The power supply appears to be a voltage doubler. For this supply to operate correctly low ESR caps should be used and at equal values given. The caps will heat if not low E and voltage/hum will be off if MF values not equal. If not 15's then 22mf "should" be O.K.

Sorry, can't find "c102" for any further advice I am referencing Riders at Nostalgia Air for a schematic.
Do check for leakage from C22 on 35L6 pin 5 control grid.
