    Re: Ratdude's first scope

    Doesn't XY mode involve using a two-channel scope?

    Didn't RatDude call his scope a one-channel scope?

    Or am I missing something again?

    Not trying to be sarcastic or anything... just wondering.

      XY mode doesn't involve a 2-channel scope, it only needs 2 inputs. It overrides the X axis which is normally controlled by the timebase. Differential measurements, or measurements of two different signals require a 2-channel scope.

        Based on the schematic this scope has only AC coupling on the inputs?

          I mean't. Most scopes integrate X and Y into the two channel inputs so they don't need to use 2 separate dedicated BNC jacks.
          Elements of the past and the future combining to make something not quite as good as either.

              My first scope was full of tubes and worked great since all I did was audio (1989). I also got an isolation transformer with it.

              Nice find you have there!

                Heathkit IO-4205 Power Supply Caps
                by eryjus
                Hello,

                First, I am a complete noob with high voltage stuff. I'm learning, but I need help by someone looking over my shoulder.

                I recently came into posession of a Heathkit IO-4205 5MHz Dual Trace Oscilloscope. The documentation is copyright 1978. I'm told it works.

                I opened it up to check the caps before I applied power, and found the following black caps and wanted to know what they were. They are on the power supply board. I was able to read the name and model and came up with, "Nytronics 162J-1, 0.1uF, 20% tolerance, 2000VDC."

                Reading input and output of bridge rectifier on the same scope?
                by EasyGoing1
                I have a 40 volt AC transformer that I put a bridge rectifier on, and I wanted to see the input signal and the output signal on the same screen on my scope, so I set one channel up with the test lead on one side of the input and the ground lead on the other side of the input, then I used another channel on the scope and clipped the test lead on the positive side of the output then the ground on the negative side of the output.

                When I connected the transformer to power, the wire that was connected between the ground lead on the second channel and the negative side of the bridge rectifier...

                I thinking about about buying one later on this year depending on what feedback I get from this forum members that know more than I do about what is importance about what to have in a scope

                Dial Cord Hell! Radio Shack SW-100 (Venturer 2959, Rhapsody RY-610)
                by vestaviascott
                I'm looking for the dial cord winding settings for this radio!

                I spend most of a whole day yesterday trying to figure this out. I just need to know how many turns for the tuning knob stylus to get me started, then how many on the lower and upper bobbins on the first cord pulley (there are two on either side of the tuning band area).

                The dial cord system has a central gear where the dial cord spring and stay is, then the tuning knob stylus and two small rollers each with a small and a larger bobbin holder. I finally figured out how to wind the cord on those bobbins...
