CF will do nicely. Buy KOA/Speer parts from Mouser, of an appropriate wattage rating. Remember, Kiwame "audiophile grade" resistors are, in fact, KOA/Speer.
Frankly, the fascination with "boutique" parts eludes me. Yes, there are hyper-critical situations where noise factor, low ESR, non-inductive ... matter and a costly part makes sense. Otherwise, good grade (not "bargain basement"), industrial parts yield eminently satisfactory results. Every last one of us is highly vulnerable to the "Emperor's New Clothes Virus". :>((
Are you talking about this one??
A Mouser search is linked below. The parts branded Kiwame are of the higher rated wattages. I suggest you use parts of an appropriate wattage in any given position.
Good stuff at a reasonable price is hard to beat.
Can I use Mills MRA-5 and MRA-12 for the power supply circuit?
That would be a complete waste of money . The inductance of "ordinary" WW resistors is of benefit (small) in a PSU filter. For Pete's sake, chokes ( inductors ) are part of many an excellent PSU filter.
I have no choice as some of the good sounding and dirt cheap inductive wirewound resistors do not have all value for the PSU.
However, Mills has everything I need for this purpose.
