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

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.
