Rockola 1475 Amp Restore Question

Restoring a Rockola 1475. I have the service manual and a full size schematic which has been great. There is a missing 4.5 OHM power resistor on the side of the amp that is part of the amp power supply circuit. The original part is shown as 33083, it looks like a chassis mount power resistor but the question is how many watts? Also the white Standee resistors that are vertical chassis mounted are broken off they are listed as 4500, 940 ohms and possibly center tapped and another 3900 ohm one. What would the wattage of these be if I replace with a precision power resistor. Thanks.
