Trimmer voltages and Values - Marantz 2216b

Hi there,

I am looking to replace some trimmers with bourns 25turns in my rebuild.

Noob question here, but I can't seem to find an answer. When looking at the service manual values for trimmer pots, it always lists the resistance, but can't find the correct wattage or voltage. I looked at the schematic as well to see if I could figure it out, but I'm still not good at reading those.

For example, I see 1kOhm for R719/720, but can't find the wattage.

Same with R156 listed as 5kOhm.
Should I assume 1/2W unless otherwise specified?

Thanks in advance.

Yes. 1/2 Watt. Something like this for side adjustment. There are also top adjustment versions.
