My Home-Built Tube Amplifier / Valve Amp with VFD

This is my first Tube/Valve Amplifier I built. It is a Push-Pull type using EL84 output tubes and ECF80's for first stage amplification and phase splitting. I added an awesome retro VFD Display too. There is also a switch to select to run the amp in Pentode mode or Ultra-linear output mode.
[See my other video of this amp with more technical details:]
