- Audio Tubes getting expensive and rare now. Always wanted a simple affordable Audio Tube Tester. Simple easy ...n o fancy. I did it. Give me a thumps up if it inspires you to anything!
Schematics 04:04 and Part list 03:11 included. - Hudba
very nice build, looks like a cool and well fuctioning aparatus. Great job !!!
Whoa! Nice to see another video of yours!!
Thanks for the video! I was thinking about building something like this a couple of days ago.
Thanks for your comment! I´ve wired in the missing standby switch later at the end. It was dearly needed in this case - so if you plan on making your own one - don´t skimp on that one!
Excellent
I like your form factor. Of course a solid wood like walnut would look nice too. Looks like you could resell them or sell a kit. Nice tight wiring. Kudos!!
Very nice! You probably could've made is simpler too by eliminating the "Test" mode and "Measure" everything.
I have built a complete audio hifi system using tubes from pre-amp to power output from scratch, VU monitor and everything. I got 2500 hours out of JJ EL34 standard version tubes even if I push them hard with dynamic voltage controlled power supply I built myself ( it is an external perfect DC stabilized adjustable supply from 200-500 volt that also is audio controlled which can be externally triggerend and apply power when something is playing, so at idle the power amp has it´s built in supply that works around 250V so it saves tube life when nothing is playing, and with the external supply I can crank up the power enough to redplate the tubes for maximum power, good stuff
that's pretty cool
@@songshineoriginalmusic thank you :) I really should do some videos on this stuff sometime but I been really slow with that part for many reasons. But I really like this system and those who see and hear it in real life is very impressed too. I always loved tubes
lovely tester
Love it!
ok , thanks , have a good day. Alain
thanks for this video , yes that"encourage me to do the same or similar , but could you telle me what was the total amount in " €' ( or ' £ " or " $ ' ) to do it ?
thanks for your comment! ..thats a good question. Apart from the chassis parts I had lying around I invested around 140€ for the essential parts. The big resistors and things like tube sockets and switches and quiet a bit of shipping fees not included. So I think it was not cheap.
I would definitely recommend to install a heater standby switch... which I had non at the time but I installed it afterwards.
So good luck, have fun diy and take care !
Very nice. Are the schematic and BOM available as printable files?
Unfortunately not but I think its possible to take a screenshot in Full screen mode and make a printout. Thanks for your comment! Take care of you!
ok thanks for the answer , do tou think it is possible to test tubes only with a multimeter ?
No that wouldn´t be very meaningful apart from discovering a fatal short to grid or an open heater filament.
Hi Sir
Good day can share with me your drawing where i can learn from you ,
Many Thanks,

Hallo! The Schematics on 04:04 and part list at 03:11 is all I got. There maybe has to be some experimentations to be expected so..Take care, good luck!
