Philco 38-690 Candohm Resistor Wattages and values?
#8

If this helps, here are actual power dissipations calculated from my working candohms which I replaced for reliability.

Candohm 165

46 ohm section .22 Watts used 2 watt replacement
230 ohm section .88 Watts used 5 watt replacement
154 ohm section .54 Watts used 2 watt replacement

Candohm 163

970 ohm section .48 Watts used 2 watt replacement
370 ohm section .21 Watts used 2 watt replacement
2370 ohm section 1.78 Watts used 5 watt replacement
3200 ohm section 6.12 Watts used 25 watt chassis mount dale resistor

My candohms were slightly off but not enough to skew my calculations. I simply measured voltage drop and did calculations using known parameters of voltage and measured resistance. Hope this helps future restorations.
