A wirewound resistor will work fine in the power
supply.  You will usually run into problems if you use
a wirewound resistor in an r.f. circuit.  But, there
will be no problems in the power supply.

For my Heathkit RF signal generator, the voltage is
125V in the secondary and the current as marked on the
schematic is 100ma. That means I need a 12.5W resistor
at about 50 ohms to start. Wow! The only 50 ohm
non-inductive resistors I have are 1/4 to 2 watts.
Would the wirewound be a problem in this application
(or maybe not since it is ahead of the filter
capacitor)?
