A trailer: Nutube, an incredible new vacuum tube technology in 21st. century

This movie is a trailer of my next making. You will know VFD, a bit old vacuum digit display technology but this VFD is totally different. It's purpose is not showing data, digit but amplify signal. YES, it is a triode!! This package contains twin triode and we can design amplifier by this tiny device, requiring very small voltage!. I've already designed circuit and now waiting for delivery from China's PCB service. As same as my another project, I will sell a kit at tindie. https://www.tindie.com/products/microwavemont/nutube-amp-kit-a-vacuum-tube-in-new-century/ Stay tune!!
