Model 650-121 - Mike Stover - 03-26-2018

New to the Phorum.  Been restoring radios for about 15 years but not a lot of Philcos.  Have a question for the group.  The schematic in Riders volume 6 shows resistor #66 as a BC Wirewound 3 section component.  In the bias circuit for the drivers and output. The one in this chassis has been HOT!  Cloth covering is charred and mostly missing.  Values I get are 10 ohms, 67 ohms and 67 ohms.  Should be 10 ohms, 110 ohms and 130 ohms.  Planning to replace this component with three separate components BUT not sure what wattage I'll need.  I think 10 watts would work but not sure.  Any help would be appreciated.  Mike
