    Lenire Tinnitus Treatment

    Well it took an MRI to find my inner ear problem! The Cat-scan didn't show anything. No it wasn't fun, but it's good to know what has been causing my symptoms for over a decade.

    Random Technical Picture Upload Thread

    It might be interesting to look at some forums visits from year to year. I recall a few forums being very active before the COVID lockdown and now are a shadow of their former activity.

    Circuit breaker - which to choose

    The primary task of the Protective Earth/Safety ground conductor is to trip a circuit breaker in the case of a Ground Fault (Short circuit). True there is continuity to Planet Earth, but it has little to do with day-to-day AC power quality.

    Extreme Snake Oil

    PTFE insulation and a silver plated core wire are great for a coax cable being used above about 100 megahertz. But they don't do anything good for an audio frequency cable.

    Popping a 5000 Amp Fuse

    At my old R&D day jobs, one of the engineers took several large fuse to the Tennessee Valley Authority test facility. At the facility they had a bunker for the testers while they blew things up

    25' unbalanced connection between amp and pre-outs

    But a simple coax with a heavy braided shield will be better. The lower the end-to-end resistance of the cable shield/ground the better.

    25' unbalanced connection between amp and pre-outs

    Getting back to long RCA interconnects. a] Coax cables with heavy braided shielded are best. Like: Canare LV77S, Belden 1505F & 1695 and Blue Jeans Cable LC-1. But 5 cables all from one unit to another unit reduce the need for heavy shielded. The heavy shield is more about amp to speaker...

    2024 Total Solar Eclipse

    While we live just about 7 miles from the center-line path. A local TV Meteorologist statistician, thinks that there is about a 70% change of it being a cloudy afternoon. And the baseball team's Opening Day starts 2 hours later, which almost guarantees poor weather.

    Do you think superconductors will make a difference to audio??

    First searching for a room temperature superconductor solution. Then searching for an audio equipment need for that solution.
