it matters.
look on the schematic, the there is a voltage divider that puts about +40vdc bias on the heater lines. This is required if you look at datasheets (although anyone doing ampheads mods is not doing this).
You could either parallel them for 7 amps (which means you will probably have too high a voltage). ot just just one (ez81 ~ 1amp, 2x 6dj8 ~ 0.6amp, 2X 6n6p ~1.6amp = 3.2amps @6.3v.
If the tranformer runs a bit hot, then parallel them (taking care of phase).
