RE: resistors

You'd need two 10W 1600 ohm resistors. When you put resistors in parallel,
the effective resistance is
R = 1 / ( 1/r1 + 1/r2 + ... + 1/Rn )
If all the Ri are equal, then R = R1/n, e.g., two 1600 ohm resistors in
parallel give an effective resistance of 1600/2 = 800 ohms.

Is it ok to use two 10 watt 800 ohm wire wound resistors in parallel
instead of a single 20 watt 800 ohm resistor in an r/f filter circuit? If
so this is about 50% cheaper.
