Question Aleph 2 and resistor wattage

I appologize if this has been covered before, but I can`t find anything conclusive.

I am building an Aleph 2 and I am trying to figure out the minimum resistor wattage for all the resistors.

I have settled for Caddock MP930 as power resistors (R22 - R27 and R40 - 51) but I am having trouble with the rest of the resistors.

Will 0.5 watt VD RN65 be sufficent or should I get some 1 watt for the remaining resistors?

Also if anyone would would care to enlighten me as to how to calculate the wattage of the resistors, I`d be gratefull. I know the basic formulas, but I don`t understand how to use them in a circuit with +- 45 volt rails, transistors, parallel and serial etc.

Thanks a lot.

Yes, the 0,5W VD RN65 resistors will work just fine. A rating of 1/4W is enough. And the power resistors should be 3W.
