IME, a 20 amp iec works less well if placed vertically ( like most amps are designed..including the ARC REF 75) than a 15 amp iec if the 15amp iec is placed horizontally from a socket grabbing perspective. Very few amp designers place their iec’s horizontally, which means that the cable is always pulling down and away from the socket...not a very good idea IMHO.
Audio Research Ref 75 SE: Replace 20A IEC inlet with 15A
Has anyone successfully replaced the 20A IEC inlet with a 15A to use a good 15A power cord? I am currently using 2 Voodoo adapters: a 20A female to 15A male + a right-angle 15A adapter due to the depth of the amp causing it to come up against the wall. Less than ideal, but works fine and sounds great.
Since the amp doesn't require 20A circuit it would be nice to replace the 20A inlet on the amp with a good quality 15A inlet for a direct connection to the power cord.
If anyone has done this, which 15A inlet did you use? Does it fit well in the amp's cutout and were you able to use the existing screw on connectors to fasten the internal wires or did you have to solder them?
