DIY biamp 6-24 crossover

Hi



It says this on the biamp crossover page in the store.

  1. 24 JFETs (selected for Idss and matched for performance)
  2. 24 biasing resistors (each paired to a JFET for optimal performance)
When i recieved the parts it was just 24 resistors on a strib. Is the pairing between Jfet and resistor not nesseary?
