Making phono resistance plugs


Any ideas about making a pair? Looks simple. Any esoteric suggestions? Need a little over 400 ohm. Any particular brand of resistor, or plug?

Any RCA, solder resistor inside, screw the cover back on, connect, and listen. Don't overthink it. Use cheap until you find the right value, then try boutique if you want.
Thanks! I just purchased a Whest phonostage .20 and the only value plug is 100 ohm. My Hana SL specs are >400ohm.
