I've worked on tube amps quite a bit. To some, it' a tube amp if it has a single tube anywhere. That's just silly, IMO. To me, it's a tube amp if the signal chain contains tubes and no solid state. If the preamp or power amp are solid state, it's a hybrid. Trem oscillator? Don't care. Rectifier? Don't care.That's funny. I read someone saying that a tube amp wasn't a tube amp cause it had a selenium rectifier for the bias.....![]()
Now "all tube amp"? That's where the fistcuffs start with some folk. I figure if it has a SS rectifier, it's just silly to call it an all tube amp. But hey, you do you. (Not you you, but the generic you.) Just be up front about it if you're selling it. "All tube signal path. Solid state nibbling at the borders, but ICE hasn't noticed."
