OK, these are TWO different values.

The smaller wattage 470 K can just go on the actual V2 tube socket (the 12AX7 socket).

The larger 470 ohm is your 6V6's cathode resistor as you mentioned and is in parallel with the 25uF bypass cap.

1w - 10w is fine for the 6V6's cathode resistor, but it shouldn't be any lower. The old schem shows this as a 1 watt, but guys today generally use 5 watt. It won't hurt it, but going with a lower watt than 1w may be very bad :)

The 470 K is a normal 1/4 to 1/2 watt, just like the rest on the board.

Again, be sure to differentiate between K and regular ohms.
