Wonder if it still works and what you can use it for? Clem found a very old valve in his pile of parts. He quickly consults his friend Max to find out if his vintage Valvo ED tube is still working and together they start to build a high-end tube testing device DIY kit, the ROEtest V10 by Helmut Weigl. Clem also shows you treasures from his Tube collection, including some really weird vintage Valves! </span></p><p style="margin:0;padding:0px;">&nbsp;</p><h2><span style="color:#3334ca;">Supplemental Content:</span></h2><p style="margin:0;padding:0px;">&nbsp;</p><ul><li><span>Links for the Roetest V10 Main page: </span><a class="" href="http://www.roehrentest.de/">http://www.roehrentest.de/</a></li><li><span>Development log of the hardware: </span><a class="" href="http://www.roehrentest.de/hardware.html">http://www.roehrentest.de/hardware.html</a></li><li><span>The extensive Software and Tube database! </span><a class="" href="http://www.roehrentest.de/Software.html">http://www.roehrentest.de/Software.html</a></li><li><span>You need to obtain a Software license and a preprogrammed PIC MCu from Helmut Weigl to build and use the Roetest. it comes with a CD-Rom containing documentation and a BOM tool to figure out which parts you need to order. </span><a class="" href="http://www.roehrentest.de/Bestellung.html">http://www.roehrentest.de/Bestellung.html</a></li><li>Most parts can be bought at element14 stores but some specialized parts like the custom torrodial transformers and the PCBS should be obtained from Helmut weigl directly.</li><li><span>A gallery of Roetest Devices built by enthusiasts over the years: </span><a class="" href="http://www.roehrentest.de/AndereRoetests.html">http://www.roehrentest.de/AndereRoetests.html</a></li><li><span>Some useful FAQs: </span><a class="" href="http://www.roehrentest.de/FAQs.html">http://www.roehrentest.de/FAQs.html</a></li><li>Max Koschus Youtube channel, with tons of incredible vintage electronics teardowns: www.youtube.com/maxkoschuh</li><li><span>Max Koschuh eBay shop: </span><a class="" href="https://www.ebay.at/str/maxkoschuhonlineshop">https://www.ebay.at/str/maxkoschuhonlineshop</a></li><li><span>Great source for vintage project parts: </span><a class="" href="http://koschuh.com">http://koschuh.com</a></li><li><span>Usagi electric is building a TUBE based Computer in 2021: </span><a class="" href="https://www.youtube.com/user/Nakazoto">https://www.youtube.com/user/Nakazoto</a></li><li>If you need to identify a tube these sites will help and provide some good information:<ul><li><a class="" href="https://www.radiomuseum.org/">https://www.radiomuseum.org/</a></li><li><a class="" href="http://www.jogis-roehrenbude.de/">http://www.jogis-roehrenbude.de/</a></li><li><a class="" href="http://koschuh.com">http://koschuh.com</a></li></ul></li></ul><p style="margin:0;"><span style="color:#000000;font-family:Roboto, RobotoDraft, Helvetica, Arial, sans-serif;font-size:13px;white-space:pre-wrap;background-color:#ffffff;">You Cannot buy this Vacuum Tube Tester.
