what is the wattage?

[vibrating string]

I have just replace most of the caps and several resistors in an old Ampeg amp. If the resistor checks out, I leave it. I had several that had drifted significantly from the markings on them.....they will be replaced. But I needed several higher wattage resistors, including what appears to be a 10-15 Watt cathode bias resistor. The physical size of the resistor should be a good indicator of the wattage. Larry
