Here we have Cardas Audio Quad Eutectic Solder in a 1 lb roll.
George created Cardas Audio Quad Eutectic Solder for the perfect joining of the connector to the conductor. Quad Eutectic solder contains a proprietary (i.e. we won't tell you) blend of silver, copper, tin & lead. Outside diameter: 0.032"
The label on Quad solder changes with each batch. To ensure your solder is authentic, only purchase Cardas Solder through authorized dealers. If purchased through an authorized dealer, it's authentic regardless of the label.
