Resistor power ratings for PPI amp

[kcr357 10+ year member]

anyone have an idea of what these need to be?

Would 1 watt be enough? Haven't been able to find a schematic to look up the exact specs...

It's a surface mount from a ppi bk520.4

Did you buy that table from Edward Scissorhands?

Where is the resistor in the circuit? That will determine an appropriate power rating. If it is in the input section than 1/8W is plenty. If it is in the power supply section than it may be more. Power ratings will affect size so measure with a micrometer and compare with Digikey, Mouser, etc.

I do upholstery, it's my cutting

The fuse is right at the outputs, there looks to be one f9r each channel
