I know there are some Carver fans here, so I thought I’d bring this to your attention. PS Audio has a biweekly online magazine that is really quite interesting. I don’t know how they can come up with so much content every two weeks. Frank Doris is a recent addition to the staff and he has an article in the current issue (#104) describing how he was troubleshooting one silent Carver Silver Seven amp while working for the Absolute Sound. Harry Pearson and a noted music critic were waiting in the adjacent listening room. Frank was on the phone with Bob Carver and heating up a soldering iron to see if it could be brought back to life. Worth a read.

    Dude's lucky to still be alive. He is right, that can be lethal.

    I saw someone brought down to his knees (as quick as one can snap their fingers) on one of Bob's amps that had only 35 watts....and it was unplugged. I guarantee you he will never handle that amp again with the bottom cover off.

    Cool read, nonetheless.

    As they say:
    It's the volts that jolt but the mills [milliamps] that kill.

    DC is a little friendlier than AC in the sense that DC tends to knock one away from the source; AC induces some sort of muscular paralysis such that a person who contacts a serious source of AC (e.g., a bare spot on a power cord) may not let go -- sometimes with fatal results.

    Either way, the best thing is to ensure that the current doesn't go through you -- two hands across a voltage and current source tends to be what stops the heart. :(
    Thus, when working on vacuum tube circuits, the ol' Alanis Morissette song is a good mantra

    Shoes with thick rubber soles are good, too.
    I've seen [EDIT] a TV service guy (they were guys, in those long-ago days) draw a spark through a hole in the sole of one of his shoes. No kidding.
