thank you a childhood hobby re ignited in my 60s I hope you make the M3 the zeppelin I can paint the box orange or yellow with black font to give it a vibe,,,, even Pink and black is cool sweet0---sick--dope,,, new words youngies say.. a dram awakens within me

hi where can i find circuit board with the poincon thanks

I keep coming back to this video for it's purity of recreation. Superb effort

Excellent,can you explain and show John Lennons guitar solo on Yokos Walking On Thin Ice song please👍🥁

Regarding NFB, there are amplifiers using low or high impedance tap. Disregarding where you plug in the speaker, there will be voltage present on all taps of the output transformer. Grids need no current. Tubes are voltage driven, so you will not take away power by taking the NFB signal from any tap. What is important is the voltage you get from the tap. Higher impedance taps have more windings and hence have higher voltage. So if your output transformer has 4 and 8 Ohm taps, voltage at 8 Ohm tap will be twice as high. Hence, if you want a certain feedback level, you will need a bigger NFB resistor value. Higher the voltage of the NFB signal and more NFB effect you get. Initially, it sounds like volume loss. But it increases headroom and lowers unwanted distortion. Guitar tube amplifiers without NFB are wilder, harmonics generate easier and distort more. Now, regarding that 3 position switch. Those label names are just that. Any connection to that type of tone is happening in the user's brain. There is nothing like that happening when you change cathode bypass. Cathode resistor does the biasing of the tube. When the tube is working, there is a Voltagd drop over the cathode resistor. That voltage drop references the ground as lower voltage than the cathode of the tube. Hence, grid leak resistor is connected to ground, and that brings the "negative" (better called lower than cathode) voltage to a grid of the output tube and that biases the tube. So, just to do a basic job, you do not even need the bypass capacitor. Why is it used then and what does the capacitance value changes? Well when people explain how the tube work they are explaing positive path. Hence only good thing happening. Though tubes are prone to their own internal NFB because of the hiw they function. I bet this is new to many people. So what bypass cap does is reducing NFB effect and making tube more efficient. That's why people will say add bypass cap and you will get more gain (talking about preamp tubes) or add more capacitance to get more power and bass in case of the cathode biased output tube/tubes. But in reality small value like 0.68 will suppres the internal NFB effect at only high frequency and will sound like a boost in the treble. Higher the capacitance more of the sonic range will be boosted. There are online bypass calculators and you can change the components and calculate the effects in gain and the frequency response. Now calling it blackface with no bypass and tweed with some and plexi with maximum is kinda silly. I might have mixed the order. What you actually get is 0.68 is top boost and 25 is full range boost. Difference in real amplifiers is way bigger. Starting from completely different tone stacks to different output tubes to different cabinets and speakers. Different bypass capacitor value can't do that. It changes the tone but not the nature of the beast. I could write a book about guitar amplifier rectification and filtering and feel under the fingers. Whole topology and execution of the schematics makes it happen. If you look at only tube or diode rectification Fender Black and Silver face amplifiers would have had no feel and would be too stiff. Same would be true for most Plexi amplifiers. But most of them feel great to play. Things are complex and one liners do not cover it. For example no NFB loop in small power amplifiers make them feel bigger. More alive to. But from like 50 Watt and more it becomes horrible and uncontrollable and to dynamic. Impossible to play.

20:05 You are wrong about that. I always use the 16 Ohm. Remember we are talking about a transformer. To try to understand you could hook up a 8R load and measure on the 16R output tap....

Man… love this. Thank you for sharing!!

The "current limiting" safety device is called your FUSE! 🤦🏻

My new Mentor, Dave Hunter explains in a a way that i can understand and not get lost and say WTF, i want to learn all about tube amps, i just got a weber 5f2a for a price of 200.00 from a friend that got it for 50.00 worth of dope(crazy ) when i was younger i owned a Fender Bandmaster blackface66 i think With the fender cabinet that hat 2 Altec Lansing speakers, that i never should have gotten gotten rid of !!! another jem i had was a Blackface Fender Princeton amp with the original Jensen, in the words of Rod Stewart, i wish i knew then what i know now , when i was younger!!!!!! thank you for a very well vid, Jan

This is a video showing off a build, not an actual instructional build...

Really useful info on adding a NFB loop to an amp w/a multi tap Output Transformer (connecting to the lowest impedance). I'm about at the end of building a 5E3 kit, and had recently decided to modify it to include that. Great video, very informative (+ covers something there's not much info out there on)

With the ability digitally model any amp you want, including the Princeton, Who needs to build one? The answer is that it's not about need. The real question is why the hell would I not WANT another beautiful tube head sitting atop my spare 4x12? That thing is sexy AF. Great Job.

the amp used to record that first opening music tune sounds awesome now i want one of those amps

You have 2 stroke engines. Guitar amps are either single ended or push-pull

The slide and solo are by Richards. Taylor is on bass and does not play guitar.

Great video. Thanks for doing it and providing such usual info. I plan to build a Ge Fuzz soon but looking to find one that delivers the sound I want. Do you know of a kit that can get the tone like Pete Thorn gets from the Constellation when he rolls down the Strat volume at around 3:35? ua-cam.com/video/eUumA9bASxM/v-deo.html He calls it a "glassy highs thing." I will watch the other video you mention early in the video in case the sound I am after is missing. Brian

That amp would be great with a master volume and effectsloop. I am looking for a plan for a 3 to 5 watt amp with reverb or effectsloop to make a small top. Ideas anyone? Also a maser volume is a must. A cranked Champ sounds great, but it is too loud for my house and effects have to go in the front. This amp with volume, tone, master volume and reverb/effectloop.

Very nice video! The tone and play of the main riff is great! But, altough there's a slide guitar over the entire song, it seams to me that the solo is not a slide playing. In fact, I see a lot a Keith work in there, with that "chuck berry" style begining, bends with double stops and so on.

Great job breaking this down. I never realized the tuning was off until I just learned how to play it.

First mention I have ever heard of a two stroke Amplifier....I mean I have heard of two stroke diesel engines,, automotive..such as SAAB ....and others two stroke motorcycles like the 750 triple Suzuki GT we dubbed water buffalo...and I have messed with amplifier off and on since I was a little Ladd....Goes to show..I am not a know it all... after listening and watching I now know why....Rock and Metal was always my interest....But this is a sound I have learned to love these days. Thanks glad I discovered this... Very interesting 🤔

With respect the only thing right about this video.is the capo is in the correct place

It was getting interesting until I googled the rip off price!! How much?? For that?? And you have to build it yourself?? Lots of gullible folk in the snake oil amp business

I've built several variations on the 2 Stroke theme and they're all the best amp I've ever heard.

Are you sure about the working of transistors / valves?? I have learned that valves are voltage controlled current devices. Aside from that I had a VOX fuzz when I was young, I suppose it was a V 1.5. I got it around the time it came out, together with a VOX AC30 Top Boost. Happy times 🙂 At that time I/we were not aware of the guitar volume controlling the Fuzz pedal.

Really wish there was a sound sample of this kit.

I've heard it many times by other guitarists---only they know the right way to play their own riffs--almost all of them say everyone gets it wrong. I will leave the originators to be the experts. Unfortunately, Mr. Allman is no longer with us to tell us the right way, but I betcha Eric Clapton could tell you you're playing it wrong

Crazy clever way to bring the puzzle of this song into the light of understanding of how it’s made. Thanks for the big share? 💪🎸 🤟

The video is very professional and well put together. It has the format of a Masterclass, thank you!

john dowd music guru genius such creative spaces

Just found this channel and i just want to THANK YOU a lot for making these videos. I basically never comment on videos but this channel is GOLD. You have one more follower and subscriber now my friend! Thanks for this! Let's see this channel grow dude! Good stuff should be on top. ALWAYS.

it really sounds inspired on the Rolling Stones bassline ✌️

This is gold. Thank you!

дед хуйней мается

Tune your guitar before you post a video on the internet 😂 oh and play it right too

That's a fancy garden bench you got there, with the little table that pulls up from the seat

Excellent. That takes a lot of talent & time. Thanks for sharing both!

I wonder what the issue with your princeton build was? I built mojotone's champ kit a year or two before this video came out and it's a great amp. That said my main practice amp now is a Monoprice princeton clone I got for $99 with the output switched to a 6k6. The plate current is different but I've had no issues I wanted more breakup at lower volumes.

Thank you so much, this was brilliant

You should think about a CTC video of Keep On Growing by Derek and The Dominos.

Layla, forever!! 🔴🎌

Добрый день, дорогой друг! Делал эту примочку на советских транзисторах. Примеры звучания есть у меня на канале. Сейчас, когда смотрю твоё видео, улыбаюсь и вспоминаю как много я не знал подводных камней и твое видео показало мои мысли и решения, которых у меня тогда не было. Спасибо за видео. Здоровья, добра и удачи, дорогой друг! С приветом из Санкт-Петербурга.

love this song and I love Duane but his solo on this track is quite possibly the worst in music history when you isolate it. when mixed somehow it works.

Hi , Cannot thank you enough for this video !!!! I am a retired Cabinet Maker , Guitar player , and have been inspired by you video to attempt to build a Two -Stroke amp , I have the Dave Hunter book and am in the process of purchasing all the components needed . Today I studied the layout plan of the amp and found what I think is a mistake !!! I'm a novice electronics person so can only express it thus . At the centre of the board there are 2 capacitors that are .220 uf which are in place , but to the left of those there is a figure .25uf/50v , but there is no symbol showing this component in place . Please could you say if this is a printing error . Thank you again . Peter , Herne Bay UK .

When they found Carbone in the meat truck, he was frozen so stiff it took them three days to thaw him out for the autopsy...

This deserves way more likes. So good.

I don’t understand comments saying “this doesn’t swing”. It can’t swing like the Stones, as they aren’t playing here!! But it is a great analysis of the song and it’s construction to enable amateurs like me to play different components of it. Very interesting and I appreciate the effort put into this. Thanks!

Great video, very informative. Layla is up there with best ever classic rock songs.

I never knew you could go beyond the frets but Duane never seemed to be one for rules or boundaries.

Please do a Cracking The Code on Keep On Growing.
