R8 dissipates around 1,5-2W, so here you need an 5-10W resistor. (two 1K-5W paralel, or two 220ohm-5W serial)

R9 dissipates around 5W, so here you need a 10W resistor. (two 100K-5W paralel, or two 22K-5W serial)

The other resistors need to be 0,5W rated. As anode resistors (R3) you can use 1W or 2W rated 220K resistors for safety.
