Phil,
 A 5 watt resistor will not be large enough.  I know as I tried one plus I think I calculated it needed at least 7.5 watts. Instead ofmy retyping everything . Look at my post in Electronic restoration.  WW resistor wattage 6452. Probably half way down the column. 
   The 12 w resistor worked nicely and ended up sinked to the chassis to help it run cooler. I replaced the 185 with a 2 watt which was over kill but I had it in stock.
 If you have any other questions feel free to pm me.
                                       Good Luck,
                                                 Henry
