Tube Tester you can build yourself.

[@LA6NCA]

Uffda. IMPORTANT!!!!! Diodes must be connected from the opamp input pin to +15V power and -15V power. This is to protect the opamp. There will be a drawing on my website. www.la6nca.net/homebrew/tubtester/index.htm

Excellent. Please post website url here. Thank you. Fernando n2fq/6

The english language explanation was excellent. Great project well explained.

[@RonanCantwell]

The automated voice works well although your English is more than good enough and sounds better.

[@dicko-200]

which page please?

A separate web site for this valve tester would be very helpful. The English speaking voice is OK and so are the subtitles. Nice project. Music was a bonus. Many thanks. Best wishes.

[@LA6NCA]

Thanks for the helpful comment. It's fun making videos when I get nice comments.

[@basiljackson9318]

Fantastic job and great sounding tubes demonstrated.

[@johnrayfield11]

The english is quite good, but you know, I like to hear your voice and read the subtitles 😄

Nice project and beautiful song!

[@hansibull]

Excellent work Helge! That's quite a neat tube tester. To be honest, I prefer when you speak Norwegian and translate your script into English subtitles, but the synthesized voice was surprisingly good!

[@ebones6957]

Excellent design, very practical. Thank you for sharing

[@robertvandersanden]

Interesting project, thanks for the video. As for the voice - I prefer to hear you and read subtitles.

[@GuitarNewby]

You have some really good episodes. I always enjoy them. Especially the old WW2 equipment from Germany. I'd like to see more of the RV and G-Wagon in ham radio videos 👍.

[@LA6NCA]

Thanks for the suggestions. Great to get such input.

[@OldFoxRadioCompany]

Fantastic, well done !! thanks for sharing

[@davidgrey943]

What a great idea for testing a wide variety of tubes with a minimal outlay of cash are you happy for the viewers of your channel to copy the schematic to build their own version of the circuit. Another great project from you.

[@LA6NCA]

Thank you for the nice words. I hope more people will make one.

[@arampak]

I’ll definitely undertake this project when details of the schematic are available. It’s so much better for amateur use compared to factory tube testers that were used by technicians when they had to fix tube equipment in batches and wanted to save every minute of their tedious work.

[@LA6NCA]

Thanks for the comment. Schematic is in the video. I will make a website later.

[@pietpaaltjes7419]

Nice project. I think your English is good that I do not need subtitles. Practice will only make it better.

[@sincerelyyours7538]

Amazing! It looks so simple when you make it. I will definitely add this to my list of must make projects!

[@ritchardbookergrieco7872]

great video thank you for sharing 👌🏻👍🏻👍🏻👍🏻

[@bietfried]

The english speaking is fine. Understand all well although my english knowledge is quite limeted. Great tube tester. Excellent work as you always do. Please make a separate website about your tube tester. Thank you and greetings from Germany! Matthias

[@LA6NCA]

Thank you.

[@Xsiondu]

This was an excellent video. I'm thrilled seeing all the tunes in operation.

[@grahamogle6332]

Excellent project, well done for putting it all together. Another piece of test gear to think about building! English voice is okay, but you sound better.

[@larspregge6420]

The music is really nice.

[@alejandrovidal1607]

Added to my to do list!!!

[@AudioFanMan]

Thats fantastic!! I 100% plan on doing this... I have built a few tube amps and preamps, but am not 100% sure of the BOM.. would you happen to have any thing already written down??

[@jerryshore8374]

Thanks Helge. I am collecting parts to build one.

[@gamlemann53]

Du lager fantastiske ting Helge! The best from LB1NH 🙂

[@LA6NCA]

Thank you. :-)

[@pepehorowitz]

Nice build!

[@zdzisiek1979]

Ładny praktyczny miernik. Ciekawa konstrukcja ... Pozdrawiam

[@bjornstromberg7975]

Snyggt jobb! Men behöver en hel del kringutrustning för att mäta rör med denna. Men en del tips kunde jag nyttja. Tack!

[@LA6NCA]

Jeg har stor glede av å jobbe med denne. Fint å kunne lytte til rørene.

[@davidjenkins-oq8lc]

Thank you.

[@genadijusnovikovas8459]

Nice job!

[@JulioGutiérrezdiaz]

buenos dias muy buen trabajo y muy explicativo

[@MrSatansho]

thank :)

[@bborkzilla]

The robot voice pronunciation is quite comical at times, particularly with words like "Kilo" and "Anode." I'm OK with reading subtitles!

[@LA6NCA]

Thanks for the comment. I need to learn how to use this in a good way. I can practice speaking more English myself.

[@p1nesap]

Same, prefer closed captions & listening to Norwegian. Or, dub your English over video, it's good enough. This voice doesn't know basic pronunciations. Cool vintage tubes!

[@tim46767]

Awesome. TY

[@notegoodluck3546]

Very nice 👍

[@RikardNordin]

Engelska eller norska går bra, men jag hade hoppats att du skulle sjunga själv 😊 Hälsningar från Mullsjö

[@mooaonmaxsound9301]

Hello, I want to build your tube test circuit. I would like to ask for more information. For the current limiting resistor, 6mA, 30mA, 150mA, what value do you use? Thank you in advance.

[@accountant1653]

👍👍👍👏

[@carsten6707]

Vilket fantastiskt bygge Helge! Jag har en del gamla radiorör hemma. Skulle vara riktigt kul att bygga en sådan testare. Finns det kopplingsschema att köpa hos dig ? 73 från Dalarna

[@LA6NCA]

Takk for kommentaren. Her er skjema: www.la6nca.net/homebrew/tubtester/index.htm Det kommer mer her.

[@maxjakobsen5526]

Always hold the socket when removing a tube. Otherwise, you risk pulling it apart. Den engelske tale er nem at forstå. :-) ( gætter på du forstår Dansk )

[@LA6NCA]

Thanks for the information about the tube socket. I have received comments on this on Facebook. I did not know this even though I have worked with tubes for many years. Great to hear from Denmark. I'm there a lot with our motorhome.

[@maxjakobsen5526]

@@LA6NCA The glass flask is glued to the base, especially old tubes can slip and tear the connections.

[@maxjakobsen5526]

Mit Engelsk er ikke så godt som Norsk og Dansk. :-)

[@poma54]

You would pass the STL

[@noel3422]

Actually you can check for shorts, microphonic's and life strength just by plugging the suspect tube into a working amp.
