I'd like to upgrade some of the parts for my stock Dynaco ST-70. Values are easy to find, but not necessarily ratings, especially for resistors. I'd like to replace the two 10K bias resistors (the pots seem fine). These seem like they might be 2W but i can't be sure.
A bigger wish would be to find a list of all parts with ratings. If anyone has seen such a thing could you point me to it?

The parts list doesn't have the ratings, but you can work them out from the voltage drop across the resistor.
RN70D resistors will work at 1 watt and I remember using those in my ST-70 long ago. I rebuilt it with all metal films and Mylar caps and didn't like the sound much. Not believing resistors have much effect, it was probably the Mylar caps, or just the basic sound the amp itself. Try to use polypropylene.
