Half of a 33-3408-3 filament resistor is bad and I'm looking to replace the whole component. It is a 40/80 ohm. what wattage value would be appropriate?
TIA

Actual dissipation is abt 3W BUT if you don't want a flaming hot resistor go w/abt X3= 7-10W.

For power resistors I triple the ating, so for 3W it is 10W for me.

Thanks Terry. The math works out to 2.4W X3 Looks like 10W should cover it.
