A 6V6 is a mini 6L6. Have you ever heard one? They're a very,very clean running tube. 6V6's have always been one of my favorite tubes, more so than the El84. This is a true HiFi tube designed for purists - well, maybe not specifically for purists, but you could have fooled me.
The 6V6 breaks up later than a EL84, making them a wonderful choice to design an amplifier around. They require very little filament current (equates to LOW filament EMI) and are high gain. Good sound born of efficiency- there's nothing like it.
I am going to make more after this one goes simply because it's such a wonderful tube and the audio community should get reintroduced to them.
