What is your favorite tube type?


With so many tubes that do different things and have different sound profiles, what is your favorite? EL34s wonderful PRaT, KT88/6550s smooth and dimensional sound, lush mids of a 300B, detail of a 2A3 or the huge soundstage of an 845? I am curious which is your favorite. What do you like about it?

A lot depends on how these tubes are used- and the output transformer (or no transformer at all) as well!
It all depends on what speaker that I am using. I like the bigger brighter sound of the KT88 with my current speakers!!
I love EL34’s. Smooth Highs, Engaging Mids and Rich Bass. Currently using Russian Tung Sol EL34B in my LTA ZOTL40 Power Amp.
Best PP low watt power tube: 6BQ5/EL84! A pair of these (15 watts) with an Altec Valencia or an Altec 19 will get you halfway to audiophile heaven! Used as a quartet in the famous Vox AC-30 guitar amp!
