altec model 19....

Use 12 GA 99.99% silver wire and solder with 3% silver...........ok, that's pretty esoteric.
14 GA romex ground wire makes a good buss bar.
Solder with 2% or 3% silver is alaways a good idea. In fact run the heavier gauge wire to the terminal strips on the back of the x-over as well.

Very good suggestion when considering the "less that ideal" original wire found on the model 19 crossovers.
