    Vacuum Tubes (Valves)

    A (CME) Coronal mass ejection from our son colliding with the Earth's magnetosphere would be one hell of an EMP. I would put good money on vacuum tubes surviving but no one else... Long live vacuum tubes.

    Help to identify/replace component

    Do you have the owner's manual it'll tell you the operating current. The 0880-20 suggest it's 20 amps but it could be wrong what is the battery pack say on it? You said."Current being the volts and amps?" The answer is no. But you're really close.

    I read somewhere that the dots and dashes of Morse code are in demanded in fashion and jewelry so you can hide secret messages stylishly.And composers use it to spell out words in the rhythmic patterns of musical notes to create a hidden message in a piece of music. I hope I'm not being paranoid...

    Vacuum Tubes (Valves)

    I've always wondered why it comes naturally for human beings to consider even harmonics musical enhancing the fundamental frequency while the odd harmonics are rough gritty sandpaper. It is understood that solid state produces square waves distortion. But I don't think it's the technology it...

    It's a wave guide, kick it in the in the gluteus maximus. It's a mechanical tube if you put a dent in it it will no longer resonate at a particular frequency (attenuate) the bottom end... no more suffering. And you're wrong! It's all about that bass... :cool:
