  1. RADIOATIONMAN/HAM/CB – Chyna caps are the 21st Century plague on electronics! They’ve been busting their seems and pissing on circuit boards for decades.

    Flashback to the early 70s – In my young and stupid days I took disassembled a lytic (with the rubber plug) and filled it with gunpowder, put some nichrome wire across the leads inside and wired it across the 6.3V filament line on the inside of an old metal Zenith chassis of a console TV and told the new guy to work on it. As you may know, you would put your left hand on the power switch while looking around at the back to see if the filaments lit up, then turn it on. Well it lit up alright with a BOOM and a big cloud of smoke! Scared the shit out of poor guy. Everybody standing around was in the joke were all surprised at how loud it was! Nobody was hurt (due to that steel chassis) and we all got a good laugh out of it.

  2. @Harry, we used to slide a piece of shrink tubing into whatever our victim was testing, then blow some cigarette smoke through it and watch them scramble for the power switch. Some very thin solder around the AC plug contacts would give a good flash when it was plugged in, and the evidence disappeared. A piece of paper slipped between the contacts on open frame relays would test troubleshooting skills. Jamming radios with signal generators, etc etc.

  3. Wild Bill – the guy in the unit next to us (in a business park) would turn his stereo up to ear-bleeding volume and shake our walls. THUMP, THUMP, THUMP TUMP. We took one of our RF generators (part of our business) modulated with 20Hz at 75kHz of deviation and swamped him out. 20Hz would then shake the walls (and tear his speakers apart) but not for long. He’d change to another FM station and we would find it. BRRRRRRRRRRRRRRRRRRRRR.
    After about 10 minutes of playing Spectrum Hunt, you could hear the swearing at the top of his lungs!

  4. Harry – I would tune a receiver to an open channel and use the noise as an external modulation source to the sig gen, then slowly turn up the output level. They’d be swearing and beating on their radios as they got noisier and noisier.

    I found a way around hunting for the station they were listening to – a spectrum analyzer with a tracking generator. I’d set the sweep to 88 to 108 Mhz and crank the sweep rate way up. Connect the tracking gen to a small RF amp to boost the signal a little, but I could jam the whole FM band with what sounded like a buzzing noise.

  5. We had the sweep function too, but we later we found a more entertaining methon by modulating with Classical or Jackie Gleason sleep music. One moment he’s listening to country or R&R, then the music would stop and Melancholy Serenade would start playing!
