Really cool amp! I love tube amps, they add so much character to an audio signal (depending on the tubes of course). My only ones are cheap chinese DIY kit pre-amps using 6J1 tubes (I REALLY need to upgrade those to something like the GE 5654W - I read they sound really good...). I use them to juice up the sound of my digital synths.... Anyhow, thank you for your great tutorials! Cheers, Tom
