I have a nice s/s amp that I'd like to keep healthy. I've typically flipped it "on" while the gain and volume were in the last settings used, but it occurred to me I might be slamming juice into some delicate-yet-critical electrical part with starting watts that could lead to failure. Then I wondered, "maybe I should turn down the volume and gain before turning it on. I should ask the collective." Am I worried for no reason? Or is it the best practice to turn down the amp first? I suppose the same question applies to tube amps, which I also use. Thanks for any info.
