    Dear Uncle Doug. May I thank you for the time and effort you and Rusty have put in to make these you tube videos. It's a pity that in 1974 when I was a College student studying Telecommunications we didn't have such superb AV lessons !. Kind regarde from England UK

    Thank you so much for these. I have learned so much, and the level of your lectures is just right. Your style, and even your handwriting, remind me so much of my Dad, who was an electrical engineer and taught me a lot. He passed away in 2001, and listening to you is almost like getting to sit next to him again.

    Hi Uncle Doug. I am a 20 year old portuguese electrical engineering student. I am also a guitar player for 10 years now. I already built my own transistor amps and effects pedals. I am digging into tube right now. Just want to say thanks for ALL of your videos. Such a nice gentleman. Hope you are doing good on this horrible lookdown. Cheers

    I'll keep them coming then. I'm a guitar player of 26 years. Spent a large portion of my 20's & 30's bouncing from wiring houses, building them, and escaping all that land based stuff and working on a commercial fishing vessel.
    With the limited electrical knowledge that I have your videos are a huge help bringing me up to speed on the things I need to know to build my own tube amps.
    I have always been curious about tube amps and recently bought my first, a Mesa Boogie Roadster, and I am hooked. I spent months researching different amp types before I finally decided on the Mesa Boogie.
    It was during my research that I came across your videos and it has sparked a NEED (funny what you can get addicted to) build my own amps. I have begun collecting tools and a few books that should help me in that quest. I have about a billion questions and your videos are answering a lot of them.
    Thanks a million for all the work you and Rusty do. Can't wait to learn more. .........og.

      You're welcome, Bruno. I think most of us were fairly young (or not yet born) during the heyday of vacuum tubes.

    Man these videos are excellent. I'm a service engineer working on Mass spectrometers and a keen guitarist and always wondering in detail how tubes worked and how the design of them changed the input signal.
    A bit like our Ion optics elements and quadrupole mass filters in our mass specs except for elections rather than charged ions. And instead of tubes we use electron multiplier horns for signal amplification. I can feel myself going down a deep rabbit hole here and I love it.

    As usual, I learned a tremendous amount of useful information, this time about those not-so-mysterious tubes. Just the topic for dinner table conversations, and with a new pair of paws on the camera, the video is steadier than ever. The exposition is as engaging and informative as ever. Amplifier design appears to be about balancing trade-offs in every part of the circuit, so it can only be understood by grasping the intricacies of each component in the whole.

    Awesome video series. Electronics engineer past 30 years and got my first tube headphone amp a year ago. All I can say is the sound is WOW....until it started to malfunction. I must learn how this advanced alien technology works...as one of my 6080 outputs has a bias current problem. Not the tube and I have replaced all bias resistors etc... Very low bias current..as in 1-4 mA instead of 30 or so. I cannot go back to my solid state amplifier now...it has no "soul"; just harsh, dry and cold.

    the guitar signal's "jumping on the merry-go-round" which is spinning already, and being flung off butterfingers to the next ride... - I grab it... wow.

    The way I was taught how Triodes worked, (a long time ago, (sigh)).
    You're in a room facing a white wall with your back to the window on a sunny day, the blinds are closed. As you open the blinds more light gets through. The Sun is the Cathode, the blinds are the Grid and the wall is the Anode.The less light that comes in, the lower the voltage on the grid. Just thought I'd share.
    Oh and the most precious book I own is the Telefunken 1966 book of valves. 613 pages of tech info for (almost) every single valve made. Audio/Radio/CRT/Transmitter and rectifier.With some even having example circuit diagrams. It's always been close at hand ever since I got it in 82.

    Another great vid, thanks so much. I've built a good handful of pedals but was always intimidated by tubes and their required voltages. After subscribing and watching your videos for the last 6 months or so I'm starting to feel more confident and looking forward to building a champ or 5e3 sometime soon. Thanks for lifting the veil of black magic off of these little glowing bottles!

    • @UncleDoug
      @UncleDoug  9 лет назад

      Hi, Bob, and thanks for your kind assessment of my videos. I try to present information in a way that I personally could best comprehend it. Effective teaching requires a significant amount of empathy....which is (sadly) often lacking in most venues.

      Thanks, Tim. Rusty and I are currently working on Part 2.....so stay tuned. Meanwhile, I can see from your Crosley WLW pic that you must be a radio enthusiast. Please check out a photo on my FB page: Uncle Doug's Vintage Amps, of a near-mint, completely original (and working) Zenith Stratosphere 1000Z I bought from the office of a local custodial supply company many years ago. It just proves that you should never give up looking for old treasures.....and that they are often found in unlikely places.

    Again, I enjoyed your straight forward and thorough discription of the different tube types. I have never seen many tetrodes, but they were used in the NARCO VHF radios, and I often wondered why.

    • @UncleDoug
      @UncleDoug  9 лет назад

      Thanks, SJ. You're right, those of us who work primarily on amplifiers rarely (if ever) encounter any true tetrodes. I didn't know why until I did the research preparing for this video. I guess they just got passed by during the rapid evolution of amplifier tubes.

      In Part 2, and I don't want to "give too much away", but we will discuss the development of tubes like the 6BQ5, 6L6, and KT88, which are near and dear to the hearts of all guitar amp enthusiasts.
