This series is absolutely incredible. What a time to be alive where this niche info is so easily accessible. Thank you for putting together this series! I love that you don't assume your audience has any prior knowledge on this subject, and instead of either assuming we do or going over every little excruciating detail - you guide your audience to the relevant materials IF they need to review it. You are an excellent teacher and I look forward to watching more of your videos. Thank you for your service!
This is great! Thirty plus years ago, as a navy submarine sonar technician, half of my job was repairng high powered amplifiers in my sonar gear. Once I got out of the navy, however, I drifted away from electronics. Now I'm getting back into it and don't you know I've become rather rusty at things like reading schematics. As I plan to work primarily on vintage guitar valve amplifiers it's like going to work on scaled down versions of what I used to fix in the navy. This video is a really nice refresher to drag out the information I used to know almost instinctively but has faded due to disuse. Thank you so much!
Thank you so much for this. I have my first amp kit being delivered next week. This has cleared up a lot. Now I'm just a little bit overwhelmed and not totally overwhelmed
Love your work I am 52 and can remember my pop how was a electronics repair man way back in the seventy's in his shed which I wasn't allowed in if he caught me peeking through the old stained glass window he would chase me but id sneak back especially at night to see the glow from all those tubes he would have some in tester some running in equipment to a five year old it seem to be a scene from a Franking stein movie lost old pop a few years later but now I play guitar and have a lot of tube amps im trying to learn how to maintain them and build one still have a love for tubes Thanks a lot your methods of explaining makes it easy to follow so cool.
I took electronics in the 70’s when tubes still were used, maybe I was too dumb then, or my profesor made things complicated, but I was so confused that I ended understanding very little. Now here, I get a more clear understanding of how circuits work. Thank you I’ll keep watching your videos, I want to build me a tube amp.
Good video, beautifully described. For anyone interested, the KT in KT88 stands for 'kinkless tetrode' as this has a beam forming plate to correct the characteristic kink in the tetrode curve. This was designed by the MO valve company (Marconi - Osram) in Hammersmith London following the earlier KT66 which along with the 6L6 from RCA in 1936(?) were the first of their type. (I think RCA were first).
The information you provide with your videos is truly invaluable. As an electrician, I understand the working principles of electricity, but have always been a bit intimidated by the complexity of electronics. Your videos have helped me gain some understanding of this stuff, to the point where I feel confident in rebuilding my Pilot 232 power amp. I had planned on bringing it to a shop, but after what I've learned from your videos, I think I will take it on myself! Truly can't thank you enough for providing this wealth of knowledge for everyone to learn from!
I love your videos! I've worked with tube amps and other electronics for 13 years bit it still nice to "brush" up on my knowledge. Thank you for your hard work.
I have been messing about with pedal builds and have used the rudimentary info on reading schematics that I got from my father in the 80s. It's been fun and all, but the info i have gotten from watching these videos has made things so much more clear. Thanks, man!!!!
Wow. I had a basic understanding of how tubes worked in an amplifier, but this tied it all together in a simple, practical example. Perfect. Thank you so much!
Mark, This video (series) appears to be exactly the type of "Tube Basics" that I need in order to be able to understand tube (guitar) amp schematics. Definitely a "Thumbs Up"!
Brilliant! Thanks so much. Your delivery was pitched exactly where I needed it to be for what I was looking to understand. Over the years I’ve gathered lots of good snippets of knowledge and terms about how guitar amplifier work, but your video pulled it all together for me. In particular, there was a real lightbulb moment when you explained how the pre-amp tube amplifies the AC input signal and how the coupling capacitor allows only the resulting AC current through to the power tube. Also, now I understand how negative feedback works. Cheers from Melbourne, Australia.
THANK YOU FOR THIS SERIES! I appreciate all the hard work you put into these video's. Watching these have helped me understand all these schematics i see online lol
Absoutely great, have been waiting for something like this for a long time. Much appreciated and keep them coming around this tutorial concept for beginners.
I'm glad you enjoy sharing this info. I learned a lot and will be watching the rest of the series. Just being able to see the signal path through the amp helped me understand quite a bit. Knowing where the signal path went helped make sense of how the other sections worked in conjunction with it. I sure appreciate this video. Thanks for making it and sharing it with us.
Fantastic video. Its my second time watching this after reading more about ohms law and this time it made perfect sense. Thank you so much for your series!
Thank you! What a fantastic job explaining this! I learned an incredible amount from your video. Can't wait to watch your other videos! Also looking forward to finding my next broken tube amp so I can put this into practice! At some point I am going to build my own!
Great video, thanks so much! I'm working on building some simple tube amps from forums online with documentation. The ones I'm working on explain how to build them but not how they work, so your videos are exactly what I was looking for. Thanks again!
Wonderful video. Both reinforced things i'm learning on my own and clarified things I didn't know. Wish I would've seen this before I looked at my first tube amp schematic
Watched the entire series and have learned more about VT's than I have in other vids over the past few years! Fantastic content and explanations! Finally, a vid series that answers the question "why" or what does this section do. Tip to viewers; watch the vids at 1.25 speed.
Awesome video! I'm getting into learning how guitar tube amps work in order to try to build one myself, and this video helped a lot in the understanding of how vaccum tube amps work! Cheerz from France!
Great video I agree with Spider Electron, I learned more in the short time of this video than hours I spent in school . I am really looking forward to your next production.
I just found your video :-) I alteady knew how to read electric schematics, but only a little bit about tube amps. Learned a bit more now, thanks for the very good video!
This video is so so great, i have been searching online for years to learn schematics but in vain. After watching this 45 minutes video, i have found my signal path and the reasons why the capacitor and resistors seat there. Thank you so much for the detailed explanations and deeply respect your sharing.
Very definitive explanation of the circuit with vac tubes, @ about 44:00 mins. prior to ending, you showed the current path, however my question is at vac tube 1/2 6N 1P. I understand the function of the Vac tube, so it's my understanding that part of the current feeds via 1K resistor,/100uf cap. to GND which predetermines the amount of current going into the 0.22uf cap and through the rest of the circuit to produce the sound needed. Thank you, Jay
Just an amazing resource for a beginner like me. Thank you for your painstaking efforts to explain with patience and especially so helpful to understand the 'why's' and the 'how's' . I'm looking at this in October 2022 and am grateful for these series you have put up in 2017. Just awesome. Also interesting comments from other viewers keep the fire burning...🙏
Thank you for this tutorial. It is helpful with some stuff. Other stuff I just have to rewatch till I get a better understanding of it all. Its a lot to intake at once.
Most of all thanks for the lesson, So what I learned is to use better quality componets in the signal paths. Already understood basics but the refresh was aok. I liked following the signal paths and understanding what you acheive when you are coupling and I learned a little about tube bias. I will need more here. Anyhow it was just what I needed to get me really intrested in Tube Circuits. Your methods for teaching tube circuits is right on. Thanks
Wonderful presentation of information. I’m brushing up and looking to get back into the hobby (in my case) and I really am enjoying your teaching style. It’s amazing how fruitful the same general information can be received by learning it from different people and/or sources. Thank you and I am looking forward to enjoying more videos from here as I am new to the channel. 🤠🎸
Thanks a bunch this stuff is great. I been learning this stuff pretty much on my own as I try to find where cracking and hissing is coming out of my Vox Ac15c1. Still haven’t completely harnessed the noise but this video has definitely been very helpful
Thanks for this series, it's most appreciated! Easy to understand for the novice / hobbyist like myself. One thing I would like to see you talk about is phase inverters - when and where they are needed, why they are used and how they affect the circuit. Thanks and keep doing what you are doing, I always learn something from everyone of your videos!
This is fantastic...i have a selmer zodiac twin 30 which has a fault...blows fuses...original componants so caps are probably needing replaced....you are giving me confidence to investigate and rectify
Amazing video thank you so much. You explain things so clearly. I have just started building guitar effects pedals and my dream is to be able to build a hi fi amp like the kt88 one here. Thanks again
Awesome ! Love where you used the math in Ohms Law ! Would like to have seen how the second half of the 6N1P, trying to picture it. Looking forward to push-pull !
DUH ! It just clicked while I was making a cup of coffee getting ready for the next video ! The other half of the 6N1P in the schematic would be relative to the coordinating pin #'s and coming from the second signal source ! I'm 61, gimmee a break ! 😂
Thank you. Even after 6 years of posting, your video is helpful to people like me, and will do as long as you tube exists. Thank you again.

Great job. It's nice to have an actual teacher teaching electronics. Thank you for your service in and out of the classroom! 🙌
Thanks! I learned more in 45 minutes than I've done in the past few years about tube amps!
SpiderElectron l agree with you he make a brilliant teacher
This is great learning - I understood things clearly, thank you heaps.

Simply one of the best explanations of a tube amp schematic - very clear, concise and logical - thanks mate!
Mark, your in circuit step by step diagnosis, is so clear and concise. My electronics training was solely for solid state. Thank you, so much!

Wow! Amazing video. I learned more than I did my entire life enjoying tube amps. Thank you so much!
I really appreciate this video, this was exactly what I was looking for, I learned more than ever about vaccuum tubes, thanks a lot!!!!!
I love your videos! I've worked with tube amps and other electronics for 13 years bit it still nice to "brush" up on my knowledge. Thank you for your hard work.
Very glad to see you offer this. I appreciate it and I am looking forward to the next installment.

Thank you. I've been working on tube equipment for 35 years and still have more to learn.
Between you and Uncle Doug I have learned a ton!
Excellent info. Greatly simplifies what so many assume is commonly known.
Going to have to call it a night. Definitely going to watch the next installment. Thank you for the video.
Thank you !!! I needed this as a new builder. So many questions need answering lol
This is a great series. I was never into vacuum tubes, but now I got curious.
Great video I agree with Spider Electron, I learned more in the short time of this video than hours I spent in school . I am really looking forward to your next production.
I just found your video :-) I alteady knew how to read electric schematics, but only a little bit about tube amps. Learned a bit more now, thanks for the very good video!
This video is on point. Great job. All of the concepts are very clear and succinct.
Thank you for taking your time for everyone.
This was the best video I’ve seen and I have a much better understanding now. Thank you!

Wish I had this tutorial when I learned about tubes. I used a late 1940's US Navy Technician 3 hand book. A little dry, but I got it.
I have learned a lot from this video. Going to watch part 2. Thank you
Just an amazing resource for a beginner like me. Thank you for your painstaking efforts to explain with patience and especially so helpful to understand the 'why's' and the 'how's' .

Great content and topic. Keep it up. THANX
Great! Thank you! clearest explanation!
This is excellent. Many thanks.
Fantastic tutorial, Cheers!
Excellent lesson. Thank you!
OMG This video is Amazing! Thank You soooooo much!
Excellent video, thank you.
Excellent video.
Thank you sir!
Best channel on youtube
Great video - thx for sharing!
Thank you very much for this video; very instructive.
Watching this video I realized that the B+ to ground was serving as a carrier for the much smaller AC audio signal. Breakthrough! Thanks!
You are a great teacher.
I have learned a lot! Thankyou so much
Very nice. Thanks Mark!
Great teacher! Thanks!
Excellent class. Thank you.
Thanks for your time and expertise
Outstanding! Thank you!!!!
Very good video! like it a lot!
Amazing video thank you so much. You explain things so clearly. I have just started building guitar effects pedals and my dream is to be able to build a hi fi amp like the kt88 one here. Thanks again
Great teacher. Thank you
Thanks for your efforts.
thanks. looking forward to following a push-pull amplifier project.
Great video. You're probably cover it later but I was just thinking of signal phase.
Awesome ! Love where you used the math in Ohms Law ! Would like to have seen how the second half of the 6N1P, trying to picture it. Looking forward to push-pull !
