Great series. Really informative and motivational! Keep them coming. Fan from Chicago.
One hour videos plus would be great with precise details photos and part numbers is exactly what we need.
Great job! I love this
Thanx! Exactly what I’ll need when I get around to buying a scope!
I already own an several oscilloscopes but I enjoyed the video and plan on following along so I can pick up new info as you progress through the lessons.
Thank you for a great video 😊
Very helpful and useful information. Thank you!
great video I have been thinking about starting to learn how to fix my vintage gear for awhile now . Thanks for the info to make my mind up and start gathering the things I need Great video and thank you very much
Thank you!
Excellent excellent excellent. Very informative and practical. Just was a person trying to learn about electronics needs. Thank you.
Excellent tutorial. Answered a lot of my questions. Links very helpful.
Thanks
Perfect, it's the last bit i have to aquire to begin the real work on the audio signal. I've been playing too long with swapping parts now it's time to really see what they're doing in the circuit. Thank !
thank you for sharing
Thank you, I’ve been looking for this.
Thank you very much, for taking your time. :-)
Thanks Mark!
Really good,very interesting ,thankyou
Wow bud.. really appreciate you making these.. thumbs up for sure..
Great stuff! Can't wait to get to the later ep's to apply this with my own hobby DSO work. (Y)
You are awesome. Thank you.
I'll sure be following this series.
I was given 2 scopes some time ago but not even looked at them, don't even know if they work.
Gonna dig them out soon and get my self familiar with them.
Probably the best YT video I've seen on any subject matter. I can't wait for the rest of the series...thank you.
Thanks, great video… helpful for a newbie.
Great video and good advice. Be sure to also get 50 ohm BNC terminators for your scope inputs to assure that you'll see correct voltage readings from your signal/function generator.
I had to subscribe again ! I learned all the hertz stuff in the Radio Shack books "AC circuits part one and two". Killer books
I want to get into amp repair, pedal repair, modding, building, etc. This video seems very helpful, thank you! 👍
Great video for beginners like myself. Tube stuff isn't my bag. This video is very informative and educational. Thanks for sharing your thoughts.😁
Perfect Timing. I am looking to purchase an Oscilloscope for various Guitar amplifier and pedal builds. Looking forward to watching the series....Thank you.
In ancient times when I worked at Tektronix, I used a 464 analog scope (I think that was the model). I learned to use it very well and loved it. A couple of years ago, I purchased (used) a Tek TDS420A digital scope with CRT display. Someday I might get it figured out. Like you, I grew up on the analog scopes and am struggling to get up to speed on all the menus, functions, etc., that my digital scope had. I just need to live long enough!
Great intro series for new learners and old dogs too. Those old 10 to 20 Mhz scope will serve one well, I saw 100 Mhz scopes for as little as $50 dollars a afew days ago on the web.
Excellent video. Thanks!
Happy New Year! 🎇🎆💥
Stay safe. 😷
Very helpful series. I really appreciate you doing these videos. I have an SX 1980 that I want to test out and put an upgraded power supply in and I don't know anyone close to me qualified to do it, so learning how to use a scope will certainly help. All the best and have a great New Year.
Actually, a scope will not help that much. Just checking distortion, for instance: A scope will display the waveform. Alas, even a trained human eye cannot detect more than about 1% THD. A '70s or '80s high fidelity amp needs calibrated, lab grade equipment to check THD. One problem is testing something like your SX-1980 is that your signal generator has a higher residual THD than an SX-1980 has at full power (less than .01%).
I can tell that you have many years of experience and knowledge of electronics as you explain things so well. Even though I use an o'scope and sig gen for radio tinkering, I do use audio frequencies when aligning radios. So, your video is very helpful to anyone contemplating purchase and use of an o'scope and a signal generator. Thank you very much.
Thanks Mark. It is about time some body explains this with practical applications. I learned this 40 years ago with out applications. Education is such a bitch.
When you get your amp class setup, done I am in. Will see youall in the south..
Thankyou so much.
Great timing. Just purchased a Tektronix 465.
That family of scopes has a well documented history of problems with the vertical attenuators and a bit of a PITA to work on.
OTOH, it is also well known to be a genuine workhorse
Very good video, sir. I've ended up with several 'scopes ranging from a late 40s lab model through a dual channel Heathkit c.1970 up to a 100 MHz Techtronics. For audio use on my radios I use the Techtronics or another 10 MHz scope (tube equipment) or one of the cheap DSO138 or DSO150 units from eBay/AliExpress/Bangood for solid state equipment (these are roughly $24 - $30). I have used the DSOs fed through a capacitor for some boat anchors. I plan on closely following the remainder of this series. Thanks.
Love this series. Thank you. Concerning the channel selection buttons on that Rigol, that's why I won't buy a Rigol and will be buying a Hantek DSO2D15 which has individual controls for each channel and an internal arbitrary waveform generator. It will be an addition to my Tek 465 scope and if I ever get around to repairing them, my two HP 1741A scopes.
Been in electronics for 50 years and just learned that I can still learn new things. I have the same isolation xfrmr and never thought to plug in a power strip. I am going to do this and paint it red and next to it the other will be it's natural silver. Great tip.
Wonderful info! Exactly everything I was hoping to find out. I will definitely follow all vids in this course. (BTW: Never seen a CZcams video with zero dislikes before. And this has been up for a year with 33K views as of November 2021.)
