I enjoy ALL of your videos, but I especially LOVED your delivery of this! More like this please. (this video played MUCH better in my other half's laptop and the resolution was crystal clear as well) Thanks and have a great day!

Nicholas Stokes

Thanks Paul, this has been very informative. For my education it would help to have the same thing done with early radios using 44, 36,37, and 42 tubes.

Erik Burman

Tremendously helpful! My understanding of how these circuits work has grown exponentially. Please do more deep dives like this and spare no details!

Ronald Ravenscroft

Paul That was a great presentation .I am new at this .Looking forward to other presentations on reading schematics. Thanks again.

danny smith

Yes, great elucidation. Love it!

John E Barron III

This is what I struggle the most with is understanding what is going on in the circuitry. How, Why, Where, When, What is its purpose. Please Mr. Carlson can you recommend a book or some other educational material for me to study to gain a better understanding of what is going on at a given point in the schematic.

This series is so important to us who want to restore and improve an old radio. please continue the course for us. I have learned so much in this series. its also fun to print the schematic, and take notes as I follow along. Thanks so much

Dave Bowersox

Yes, Paul, this is very useful to explain the function of ALL the components in a schematic. thanks

Bill Hall

Thank you for this presentation!!

Richard Goebel

You are an encyclopedia of electronic knowledge. These videos are the best I have ever seen. I have to watch them a few more times to get as much as I can out of them. Additional videos of this caliber is wanted.

James Eastham

This is very helpful, could you do the same kind of explanations with an AM/CW vintage transmitter like a DX60B for example. In your explanations it would be very helpful to me at least and hopefully others to verbally and/or visually if possible track a signal through a transmitter and explain what is happening from creation to transmission of the signal and the role of each component relative to the signal.

Jim H

Great series Paul - perhaps some of your most valuable videos for me. Love that you've started with tube circuits (which is what I work on most of the time, so the most applicable) but would love similar treatment of solid state circuits (where I need to learn the most).

Aidan Marttila

I am really learning a lot from these videos if you do continue this series I have a schematic that has been puzzling me for a while in how the push pull audio works

Rod Hapak

Yes, like the detailed explanations!

Alessandro Verona

Great series, your explaination always add another level of understanding to things I see daily but I never thought of in a different way. It would be great If you could do the same with a ham transreciever.

Kiara Cay Brandt

Sorry to ask but I don’t know how to PM Paul. Would someone teach me?

Dennis Cabell

This type of content is excellelent! Yes please more detailed walk throughs like this on everything!

Ragnar Elstad

Very good! Thanx a lot Paul :)

Stephen J Eskelson

Great video, do some more !

Greg Richard

OK, found it by touching the top right icon it goes into full screen. Had to touch the screen first to show the icons.

Greg Richard

I want full screen. I only want to see this comment screen when I select it.

Paul C. Humphries IV

Please continue this approach. This is extremely helpful for understanding. Thank you very much for what you do!

Sol M Del-Gado

OK, I see why R5 can't be 0 ohms. There is a feedback signal feeding into the grid(pin 5)of the 6A7M, via coupling capacitor (C45) from the inductor and capacitor assemblies to the right of the tube. R5 develops a dc bias of -5.38V. I had to print out the schematic in order to see that.

Sol M Del-Gado

I don't see how DC can flow through R3. Where does this DC originate?

Sol M Del-Gado

why not just remove the 50K ohm resistor on the 6A7M and pull it directly to ground?

Jason Martin

Yes plz

Ben Hase

These videos are super helpful. A walk through of quasi and true complementary audio output stages and FM MPX would be great.

Donald Stevenson

Definitely enjoy and receive value from these videos, very educational. Some of the theory is new to me, some is a refresher. I would like to see a similar approach on an amplifier, say from the 1970's (e.g., Pioneer, Marantz), transistor based, perhaps an integrated amp to keep things relatively simple (no tuner front end).

Eric Fox

Thank you so much! This detailed study is very helpful, especially where you discuss replacement options and considerations. Please sir, may we have some more. :-)

John E Barron III

I'm no expert but the size of the resistor and the leads are usually a give away. Watts is amps times volts so if you use ohms law and think about it the larger the lead size the more amps it can handle. Most resistors are 1/16 to 1 watt and have lead sizes from .o4mm to .8mm. Larger value resistors will have larger lead sizes to accommodate higher power. But I don't know how to determine the value by calculation or testing. Maybe Mr C. can answer that.

John E Barron III

OMG I been here on this site for about 3 years now and after watching this video I feel like a third grader sitting in class with Einstein teaching class. I'm clueless as to how you figure all that out DC here RF there AC on this side vs DC or RF on the other side. I obviously am lacking certain knowledge to be able to understand how you figure all that out. This is my weakest area being able to read schematics and trace out signals. Being able to know where things are coming from or going and at what values. Especially when they are not marked on the schematic, Ugh !

JL Riley

Love it! More please!

Laszlo Szabo

Thanks Elmer! Extraordinary presentation. Unexpectedly, I learned a lot, on a seemingly simple subject of resistors. I have three Hammarlund HX-150-s awaiting restoration. Now I am motivated to get back into the hobby. I would love to see an even more thorough explanation than what you did way back.

Jamie rygiel

Yes! Do my radio next! Haha 🤣🤞

Andrew Black

Please do continue with this series, Paul. It is very useful and well explained.

Mark Newman

Thank you Mr Paul. More content like this please!,, WB4LLP !!

Kenny Fidler

Great video Glad you’re feeling better! A double shadow circuit for the eye would be neat!

Tom Harris

Excellent. I wish you lived next door, Having a hard time with an E.H.Scott Phantom, 2 dead stages I can;t seem to sort out.

peter chambers

how do you determine the wattage of the resistor?

LoSaYa

Thank You Mr. Carlson this is the firs video I can Watch from the time you use Patreon video . its work without delays, great information,

Johan Hagens

very good explanation, thank you it's perfect! I am learning so much from you, would you consider explaning a type 465 oscilloscope from Tektronix please? Just like you did on this Prescott? Thanks!!

Lucas

Please man .ll be good more exercise like those. Awesome

Salvatore Marino

Good job P.

Stanley Benoit

Excellent job. This series has helped clear up so many questions. Please continue these classes. Can’t wait to see some solid state systems video explanations. Thank You!

Tomas Hejda

These types of videos are great. I would love to see a classic guitar amp analysis, such as Bassman or Plexi.

Marshall Lewis

These videos provide so much knowledge for other devices. I would love to see this applied through something like vacuum test equipment to so the application similarities. Thank you!

Paul Dochow

Where were you 70 years ago. I tried to learn what makes radios work way back then. There was no YT or internet, and very little information at the library. My dad had a textbook from a junior college course he took after the war, but it was a bit above my head. You have taught me more in a few minutes than I have been able to figure out in those 70 years. You explain things a simple, step-by-step way that anyone who knows the difference between AC and DC could understand. I may never have a practical need for any of this, but I feel like I've walked out of a dark fog into a sunny morning. THANK YOU!

Rick kennard

Love this type of video...please do more

Ed_G.

R4 or r5 as examples, could you make a series of values to match original value, just for grins?

Gloria Jill Sydor

absolutely more

Denis Renaud

I've been really enjoying these videos on how caps and resistors are used in a radio. I'm looking forward to seeing your future video on how to use a spectrum analyzer to align a radio.

Stephen Monteith

I find this very interesting. I'm retiring soon and would like to get into electronics as a hobby and the last two videos have help out my understanding. If you continue with this series, showing what capacitors and resistors do in switching and linear power supplies is something I would look forward to seeing.
