Awesome Home-Built Tube Amplifier / Valve Amp with VFD

My first Tube/Valve Amplifier - home-built.
Push-Pull tube amp using EL84 output tubes and ECF80's for first stage amplification and phase splitting. In this video I explain a bit about the amp.
Features:
* Outputs for 4, 8, or 16 ohm speakers
* 25 W output transformers allows headroom
* EL84's in P-P give 15-17 Watts into 8 ohms
* A switch to select operation in Pentode mode or Ultra-linear output mode.
* Awesome retro vacuum fluorescent display with different show styles.
* Included a tone stack that can simply be switched in and out of circuit with hard-wired relays as needed, to appease audiophiles! (because I like control, that's why).
