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.
Well, I can’t say I “get it” yet, but I am getting closer. I understand what you’re describing, just not the whole picture. But, you are one of the best teachers I’ve ever come across. Thank you for your efforts!
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.
@@UncleDoug yeap, I am "back to school" as I am looking for nice headphone tube amplifier diagram that is my next project - if you happen to have one please share ;-)
You're welcome, Bruno. I think most of us were fairly young (or not yet born) during the heyday of vacuum tubes. To be honest, if it weren't for the current resurgence of interest in tube electronics, it would probably all be just a dusty relic of minor historical interest. Rusty and I are glad you enjoyed our video :)
Uncle Doug! Thank you again for all your great videos - you're greatest tube guru on the internet. You help us all learn more and build better amplifiers. RIP Rusty. All love.
I would just like to thank you very much for your explanations of the guitar tube amplifier, In watching your videos for a couple of hours has done more for my understanding of these circuits then years of trying to research them on my own again thank you for your time and consideration
Great explanation of how a tube operates. Love that you include the pets! I've been a ham radio operator for 25+ years and still learn from these videos. Now if I could only get my Shih Tzu to solder.
You're the far most amazing instructor of mine ever! Thank you Uncle Doug, just because of you I'm in the tube amplifier world and feeling super happy!
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.
Wow, finally someone who was able to simplify this highly technical info. into something I could understand ! tank you Uncle Doug for being so patient & methodical. Forever thankful !
It amazing that when somebody draws the right picture, it clarifies everything. After watching a few of your videos on tubes, I could predict what you were going to say next.
10:50 I'm sure everyone will be astonished to hear Unc invented the triod back in 1906. Well done uncle Doug and congratulations on your century and then some. If you were in my country you'd have at least two telegrams from the queen by now, as well as a gong.
Thanks for the long-overdue recognition, R.D. In reality, however, it was my former assistant, Rusty, who actually invented the triode while working with his protegee, Nikki Tesla.
Give Rusty a growl & 3 barks for me. Thank you for teaching us about electrical, electronic, electronics. The world is a ocean of electrons. Getting them to flow like water where we want them to & controlling them allows us to do all kinds of things.
I have been studying vacuum tubes for radio both AM/FM and shortwave. I have an extensive collection of vintage tube radios and simply have relished your easy and thoughtful presentations! I look forward to part 2!
hey joe. do you have any circuit schematics for am/fm radio. if you have can you share it with me ? I have VT-173 1T4 tung sol lamps. I would like to make a radio.
Uncle Doug, I've watched many, certainly not all, of your videos and I feel it necessary share my appreciation of the amazingly understandable way that you present and share so much very complicated material and concepts. Thank you so much! Gene
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.
Hey There Uncle Doug & Good Ole Rusty, just wanted to catch up no muster and wish yous and urs a ''Merry Christmas & Holiday'' you've been a great mentor to us all plus an inspiration to commitment with the joy of helping ourselves to a better way of knowing more... Thanks so much!!!
You are quite welcome, Nelson. Rusty and I sincerely appreciate your kind wishes and say likewise to you and yours. We're always glad to hear that our videos have been helpful. See you in the New Year :)
Thanks Uncle Doug for all the videos explaining the parts of these magical 'black boxes' we call amplifiers! These videos you put together are great and REALLY helpful to guys like me. Cant wait till ya come up with some more!
Uncle Doug, you are truly an Inspiration! I've learnt so much from your videos...thank you so much for sharing your awesome knowledge and ability to make complicated things simple and fun things even more fun! Please never stop!
Thanks so much, Perry. It's great to hear that the videos have been helpful. As long as Rusty and I keep getting nice comments like your, we'll keep making videos :) ^. .^
Thank you Uncle Doug and Rusty. I've enjoyed your videos for a while and learn quite a bit from these more instructional videos. They really help me visualize the operations and limitations of the various tube designs/types.
Your videos really help take out the mystery of these amps we love to play through. Looks like Rusty has to step it up, Ben is taking Rusty's spot light.
Greetings, Gman. Thanks for your kind assessment of the videos :) We "babysat" Ben for a week, and during that time, Rusty passed on many of his better traits.....such as sleeping, eating, chasing tennis balls, and sleeping :)
Uncle Doug, I love these videos as when I was getting my EE in the late 80s, vacuum tubes were not covered at all. I am getting into old radios and high-end audio equipment just a little bit and your videos are far less sterile than many on the topic.
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.
I had almost forgot about how great Your channel is! Thank You wery much for uploading this serie about the AMP basics! (And thank You Rusty for great guitarr play! :D )
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!
great video's....i have never seen a series of video's like yours, you explain things in such a easy to understand way, and relaxing way, at a pace my old brain can absorb the information...i have learned so much, thank you. bob in the uk.
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.
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.
A viewer tried it a year or so ago, PC, and it took him about a week.....but he was so tired and overwhelmed when he got through that he had to go back and watch them again, slowly :) You're welcome.
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.
My third time watching all of your videos, I'm going to try to remember to like all of them this time as I am usually so enthralled by the subjects I totally forget to. (....and tighten up Rusty, you gotta make good on ya contracts)
+Ogre Badogre Thanks so much, OB. Rusty and I thrive on nice comments and lots of "likes".....so you're making us very happy indeed. This is what it takes to get Rusty back to work :)
These videos are great. I know a little about transistor theory but I'm by no means an EE, having only built a couple of pedals. Your video's are presented at a great pace, clear and most of all cover unique, inspiring projects (my fav is the mech trem). Thanks so much!
Once again, a stellar teaching presentation. This one I think is the very best yet technically speaking even though all of them are beyond excellent. I have only been at this game (building tube amps) for two years, but I have been playing on them far longer, and I have learned SO very much from Rusty, oh, and you too Doug! Thanks for all you do!
Don Palmer Thanks so much, Don. Rusty and I really appreciate your kind appraisal of our work, and are glad to hear that the videos are helpful. Best of luck with your amp and musical projects.
Another great teaching video Uncle Doug thank you! I love the little big puppy dupps! - Rusty is obviously a good teacher! - or rather was, very sad to hear.
Every time I re-watch Doug’s videos, a bit more sinks in.
That's good to hear, Will. Keep on watching :)
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

He passed away in 2001, and listening to you is almost like getting to sit next to him again.
I am quite flattered by the comparison, Jon. Thank you so much :)
Wow, thanks to these video's, it took me 45 minutes to understand the basics of a tube amp. Perfect teaching! Thank you sir!
That's great to hear, Koen :)
Well, I can’t say I “get it” yet, but I am getting closer.
I understand what you’re describing, just not the whole picture.
But, you are one of the best teachers I’ve ever come across.
Thank you for your efforts!
That's good to hear, DM. Keep up the good work.
These videos are just such fantastic learning resources. I learn so much and demystify so many things.
Glad to hear it, LG :)

Great lesson,doc
Thanks, Chris :)
This was great,
Thanks, Mr. Mac....glad you like it :)
I hope you will go over every type of tube with us, you have a good way,that makes it easier to understand the concepts.. Thanks..Cheers.
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.
My third time watching all of your videos, I'm going to try to remember to like all of them this time as I am usually so enthralled by the subjects I totally forget to. (....and tighten up Rusty, you gotta make good on ya contracts)
+Ogre Badogre Thanks so much, OB. Rusty and I thrive on nice comments and lots of "likes".....so you're making us very happy indeed. This is what it takes to get Rusty back to work :)
These videos are great. I know a little about transistor theory but I'm by no means an EE, having only built a couple of pedals. Your video's are presented at a great pace, clear and most of all cover unique, inspiring projects (my fav is the mech trem). Thanks so much!
You're welcome, Lukas, and thanks for the kind words :)
Is that first time when I understand the tubes.I have in my future plans ,to build a tube amp.👍
Let us know how it turns out, Dorin.
Once again, a stellar teaching presentation. This one I think is the very best yet technically speaking even though all of them are beyond excellent. I have only been at this game (building tube amps) for two years, but I have been playing on them far longer, and I have learned SO very much from Rusty, oh, and you too Doug! Thanks for all you do!
Don Palmer Thanks so much, Don. Rusty and I really appreciate your kind appraisal of our work, and are glad to hear that the videos are helpful. Best of luck with your amp and musical projects.
Another great teaching video Uncle Doug thank you! I love the little big puppy dupps! - Rusty is obviously a good teacher! - or rather was, very sad to hear.
Thanks so much, Neville :)
Thanks for a very interesting and informative video.
Best regards.
+GglSux You're welcome, GS......glad you liked it :)

Thanks so much. Rusty and I are glad you enjoyed the video, and got a chance to watch his teaching skills in action :)
