I would think 1/2 watt would be sufficient. The 75 isn't a power output amp that passes more current plus if you are developing only 1 volt of bias on it, that's not much. Don't forget you might need a bypass cap across it too. Also, since the 75 is the second detector too, I hope the long leads of the decade box don't do anything funky with it. It will be interesting to see how this works out!
