I'm looking for four power resistors of the same type to replace R87, R88, R89, and R90 in the POWER AMP section of the amplifier of Klipsch SW-12 subwoofer shown below:
What should the minimum voltage rating of the following new resistors be?
5W 1.5K ohm
5W 1K ohm
7W 1k ohm
7W 750 ohm
Choices 1-3 all have their voltage rating listed (350V - 500V), but I can't find the voltage rating for Choice 4:
If I can't find the voltage rating for Choice 4, should I drop it from my list of choices for the replacement resistors?
[A picture showing R88 and R90 with four other white resistors: Added 2/13/17]
There's a similar-looking row of six white resistors on the other side of the amp, too (bottom in the picture).
I received a reply from a US distributor of the Choice 4 resistor:

The max voltage rating is 500v. I don’t have a data sheet to send but the product manager was able to contact the mfg to get the voltage.
Have a nice day.

This is the resistor's listing that prompted me to ask a question about voltage rating for resistors:
I hadn't been able to find it until this morning.
