    We built our own in the early 70’s out of a OS-8 Oscilloscope. We called it a  “Octopus”.

    We always called it a "knee bender".  It also gives you a circle for a capacitor.

    OMG! Amazing watching this. Like back to basics and really well explained. I love it when people EXPLAIN EACH STEP AND WHY. I find many videos leave this out _ suppose to protect their art. Thanks buddy! Subscribed.

    I have used a device called a Rca Quick Check for 50 years. It saved me so much time troubleshooting. Octopus testers are the best.

    That reverse mounted transistor is a weird choice. But so is mounting the power switch <i>through</i> the heatsink. Weird.

    I built one of these in the 70&apos;s. &nbsp;Bolted it to the top of an HP oscilloscope. &nbsp; I also made one that connected to a high frequency oscillator - came in very handy for troubleshooting passive filters.

    <b>SUCH</b> a useful device for analogue repairs, I must have repaired hundreds if not thousands of power supplies, monitors, televisions, amplifiers etc. etc. with the help of one of these built into a Hameg &apos;scope. <br><br>Brilliant for testing individual components and if you&apos;re lucky enough to have a working board the same type as the faulty one you can race through them and track down faults/suspicious areas <b>so</b> quickly.

    So basically a component tester that comes with most hameg scopes... So useful it&apos;s unreal. Must have if you repair stuff without schematics

    I&apos;ve got an older one made by RCA model WC-528B. &nbsp;Comes in handy to see if transistors are exhibiting hard to detect resistance in the knee. &nbsp;Also have one of the Sencore Super Cricket for xistors &amp; diodes.

    We used this type circuit at NASA and WSMR starting in 1970 onward, to repair TTL logic. <br>We built our own and used an oscilloscope for display. Great little device for a few bucks you can build yourself.

    Thank you very much sir. This is the first tool I’m building to go with my BK Precision 2120B. <br>I love how YT knew I needed this video.<br>As always a pleasure being learned by Play With Junk channel. <br>❤️
