    Thank you. Based on what I’ve found on the internet it was looking like my base and emitter across my x01 was shorted. I am reading 48 ohms! Thanks for explaining the resistor!

    • @jacklick

      Base to emitter will read @ 50 ohms. That is normal as I show in the video.

      @@jacklick yea everything tests out ok but I am concerned that I tested the flyback and voltages without an isolation transformer. I am a bit confused how that could cause problems though since I am only using hot and neutral and not the earth ground. How is it possible that this could blow the Voltage regulator and / diodes?

    I watched this video and bought a CM2000, these things look super neat and I would really like to integrate this into my equipment rack. Thanks for showing this thing off.

      Yea, they are pretty cool. I have used about 1% of its capability. There are 2 additional ways to test flyback, for example. Have fun with it.

    THE LEFTOVER CAP WAS FOR THE NECKBOARD

      Appreciate the comment. You sure I hadnt replaced the one on neck board already? Lol i am pretty sure i did and it was just extra.

    I've been repairing a lot of g07 chassis's lately. I don't like the idea of replacing a flyback if the current one is good but from my research and understanding from klov is that the original ones are notorious for blowing up and just replace it when ya cap it.

    • @jacklick
      @jacklick  2 ปีที่แล้ว

      Replacement flybacks exist for g07 so it more convienent or at least an option, unlike some other chassis models. Same with width coils. I like testing and replacing only the bad parts, except caps, when i can. Good luck on your repairs

    Do you know why the "more rings" on the Ring Test is considered a better inductor or windings? The HOT transistors has an internal diode from Collector to Emitter, what is this internal diode called and what does it do?

    • @jacklick
      @jacklick  3 ปีที่แล้ว

      Nope. This is whole bit of EE that is beyond me. Damper diode but have no idea what the purpose is.

      @@jacklick what is the Test called when you used the 18v batteries to test the flyback? I'm not sure why you had to use 18vdc ( two 9volt batteries) to test the flyback ground, what a weird way to find the ground terminal of a flyback

    • @jacklick
      @jacklick  3 ปีที่แล้ว

      I just watched a youtube video, which I linked to. Since I was only reading 2v going through the flyback, I assume 9v battery wouldn't have been enough to give me a reading.

      @@jacklick I have seen this done in other youtube videos I forget the names of the videos but I find it weird to use a DC voltage to find the Secondary Ground terminal. I'm not sure what this test is called when doing this either but I have seen this done on other youtube videos.

    Is it ok to power the chassis o the bench with direct a/c and no isolation transformer if it is not connected to the CRT? I had the anode just laying there on the bench and was testing b+ voltages and listening for flyback chatter.

    • @jacklick
      @jacklick  2 ปีที่แล้ว

      I would always use an iso transformer.
