Hello Everyone,
 I need advice regarding resistor replacement in a 1936 Philco 650 chassis that I am restoring. Most of the resistors in this radio are out of tolerance and check much lower than specifications. The Rider's schematic does not list any wattage ratings. Are 1/2 watt carbon composition resistors adequate to use throughout? Several of the resistors are dimensionally very large. Any advice or recommendations would be appreciated. Below is a link to the schematic. Thank you.
Tony

When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
Circa 1966
Now I think I've got it!

Tony,
Looks like Terry has you covered.
If you email me at the address I PM'd you with, I'll email you the parts price list with values.
