What in the heck do I really need here, I am having trouble with the math here.

thanks

I have 8 25 ohm resistors , 8 16 ohm resistors and 22 8 ohm resistors....maybe I can at least use some of these?

If the 8 ohm resistors are 20W, then two 8's in series will give you 16 ohms at 40W.

If you need 25 ohms, use three 8 ohm resistors in series for a total dissipation of 60W at 24 (close enough to 25) ohms. Power resistors are like what, + or - 10% ? So three 8 ohm resistors will give you something like 21.6 to 26.4 ohms, depending on how the tolerances stack up?

What's going to get kind of silly is making an 8 ohm, 100 watt part. You're going to have to series/parallel so may individual pieces it just won't be practical.

For the 12dB cable assembies, you need a 25 ohm resistor and a 16 ohm resistor. The 10dB assembly needs two 16 ohm resistors. Use all non-inductive 10 watt parts, and build them up in blocks of four. So each really uses a "resistor block" made using four 10 watt resistors.

For the 25 ohm resistor used in the 12dB assembly, we use two pairs of series connected resistors, one a 20 ohm and the other a 30. The series connection gives 50 ohms and two of those in parallel makes 25 ohms.

The 16 ohm block is easier, since it uses four of the same part, a 16 ohm resistor. Two in series, and the 32 ohms that is formed is then connected in parallel to another just like it to make 16 ohms.

There are photos of the cable assemblies here.

Sorry for any confusion I lent to the discussion.

thanks

I still have to put in a wire to connect the parts where you see the orange line. Please let me know if I have made any mistakes.

thanks

Here is how I wired the resistors..
