    Autoswitch: AC- vs. battery-powered

    Is there a simple way to make my amp powered via the battery when no AC is available, but use the AC if it is plugged in? I was going to just put a two-way switch next to the AC socket, but maybe that is stupid.

    grease on your tools?

    What is that grease that coats all the new tools, e.g. wire strippers, electricians knife, etc. (I got them from Sears) Should I be greasing all my tools with the same stuff?

    ER-4 isolation

    All right guys, I'm still figuring out how to put these ER-4's in. I'd like to have the opinions of a bunch of people here, on how much isolation you really get with the ER-4's. (Both when you are listening to music, and when you have them in but aren't listening to anything) I thought I had a...

    I was wondering, how do amps such as the porta corba compare to the larger ones?
