In Reply to: My Vishays were all shunts to ground. Were yours actually carrying the signal? posted by hukkfinn on February 8, 2010 at 10:54:37:
At least in many audio cases involving voltage dividers such as a volume control, or input termination, and is just as important if not moreso. It is usually a higher value resistor, and hence most of the audio signal voltage is developed across it since almost all of the audio signal current flows through it.I agree with some others that the Vishay S102 is fairly neutral sounding, but my favorite resistor type is the low current precision wirewound resistors that are usually wound on a plastic epoxy bobbin core with two sections that are wound in opposite direction. I think it's called reverse pi. Then coated in silicone rubber and encapsulated in epoxy. No ceramic anywhere to give it that irritating harsh resistor sound that even nude Vishays have. Not a drop-in replacement for all applications since they do have a little more inductance in the standard winding form, but very much worth re-engineering a unit to use them in my experience.
