Duelund CAST Graphite Resistors
A step up from their standard resistors is their amazing CAST resistors. Constructed from a graphite rod with either Silver or Tinned Copper terminals in a phenolic cylinder for protection. Tinned copper leadouts are standard now. We do have stock of both. Sonically they are very similar.
Using a high-temperature epoxy as a cavity fill within the cylinder and encapsulating the graphite element. This gives each part incredible mechanical stability and incredible damping properties.
They have practically zero inductance, with a 5% tolerance. The special characteristic of this resistor is that it displays a negative temperature coefficient. For example, when a speaker's voice coil heats up, its impedance rises. The DUELUND Graphite Resistor counteracts this by utilizing a decreasing impedance. The results are greatly improved dynamics from the driver.
Diameter = 8mm, length = 65mm to 135mm.
These resistors come in either 5W or 10W, depending on the resistance.
If you are looking for a specific value, we have added a RESISTOR FILTER to speed your search up.
