Title: Do All Resistive Attenuators cause Distortion at Extreme Settings?
Post by: JustMike on November 25, 2023, 03:00:12 pm

 I have to play at "TV" volume at home and 18-20 watts is just too loud to get to the sweet spot. I like to run the volume on 2-3 which is too loud. I have a Tube Juice L-pad attenuator that when I turn down the L-pad to a very low level, I hear distortion. When I open it up a little, the distortion goes away. Where is this distortion coming from? I've read on other forums that the THD hotplate does the same thing.

guess;
speaker, you probably have so little "signal" getting to the speaker it ain't playing as designed.
while resistors a not "active" components in an AC circuit messing up 2 inductive components by starving them to death, might have un-intended consequences
