Erik is correct they have an outer copper shell and the drain wire is optional in my system I did not find a noticable difference and just cut it and sealed .it has absolutely -0 effect on the high frequencies. Parts connecxion always fails to buy ample stock
so I just ordered 10 from Hifi collective in the uk, int fedex priority
under $30 and arrives in two to 3 days max.every one of these measured under .75 of 1% in variances in 10 samples that is incredibly good. I am treating my Xover and using the excellent
milflex Copper foil .022 Bypass caps on my Xover with Duelund Silver foil with this the best resistor out there that I have heard
in North America. $25 a piece is a bit pricy but they tie in the
musical performance with great musicality and accuracy they for sure have a slightly warmer balance then the caddock or Ohmite Gold.
