As presented in the previous log, yes, VFD which has triode structure works perfectly for audio application! This time I just swapped this triode (VFD) with Nutube in my class-D power amplifier. Indeed, the sound is super wonderful, and as above picture, now it becomes my main power amplifier!!!!!!!!!

Actual operation is presented in the movie below, please check it!
