@Chuckjagermeister absolutely me too
at least the power tubes.
Are you still running mtronics jeff?
I’ve gotten shocked enough to know that I’d rather have my tubes changed by a trained professional. Ouch.
THANKYOU!
i still dont get if a 20 watt amp can power a 2.0 Channel B&W 685 speakers
whats the song in the beginning? it sounds like hendrix
Great explanation. I also have a passion for vacuum tubes and I am designing and building a Class A 5W stereo amplifier. Anyone interested in Vacuum Tubes will gain a clear understanding from your video.
So, you expected him to be shit because he Russian/Eastern Europe even though Russia used to invest huge amounts into reasearch during both czarist and communist eras.
Despite your accent troubles you managed to make an excellent educational video.
THANKS!!
‘
old vacuum tube is always HOT,,,
today no more need tube
excellent presentation!
Thank you so much for making the effort to explain this on camera. I found the analogy very easy to understand, despite having no technical backround.
Your efforts towards educating others are highly appreciated.
Good video! In electronics courses that I have taken was strictly solid state diodes as the school would not cover vacuum tubes. I am into repairing electronic musical instruments as guitar amps still use vacuum tubes, as well as older organs and Leslie speakers.
Tung-Sol was based in Newark, NJ and is long gone. The name was purchased by New Sensor Corporation in New York, but the tubes are made in China and Eastern Europe.
@davidkahan Very nice comment. Yes I remember it from the physics too Volt/meter.
Are these TUNG-SOL tubes a chinese brand? They look of high quality.
@6:57. I think you omit one factor about the grid which is the distance you put it from the cathode. The electric field is expressed in V/m so if distance is smaller, V/m is higher and you get more aplification. in other words if you put the grid too close of the anode you get little effect at all. Great vids anyway .
Thank you very much for taking the time to explain this so well to us!
PS I knew this was going to be good when I heard Jimi at the start.
Thanks man!
I like a lot the vacuum tubes. I usualyy build my circuits with it. But a couldn’t record it.
I have been a fan of tube equimpment
intelligent way to explain the basics beyond for a rookie
like me!
please dont stop to invite us with all the other terms like:
negative feedback, damping factor and so on.

Best Analogy I’ve seen regarding how vacuum tubes operate. Thank you very much, I’ll be waiting for the next videos.
Nice Explanation, Thanks man
Very nice way to explain the tubes !
Good work !!!

Love your video’s, specially the explanation about the bias current!
Good video. Really glad to find it. I’ll have to watch it when I’m not high to really understand what you’re saying. I’m enjoying the editing.
great explanation. I’ve read about water pressure etc when it comes to electricity and voltage, but your use of the analogy went above and beyond!
These are different tube amplifier pictures that I found on the web. I agree that the one on 0:12 looks a bit peculiar but I think it’s a tube amplifier.
