1 custom 5-foot DC cable. This special cable is a shielded, star-quad with 4 conductors of tinned, stranded 18AWG; paired at the connector that makes it about a heavy 15AWG. Gold/copper/brass Oyaide (5.5mm x 2.5mm) DC barrel plugs from Japan at both ends. Upon request we can terminate one end with a 2.1mm version of the Oyaide connector in case you need that size at the device end. These sell for $75 from Uptone Audio. If you have a JS-2 linear power supply and have to second source then this is your ticket. $45 plus shipping and PayPal.
