pick tube type first, then find an amp.
that’s kinda what I was saying when I listed all the tube types I have heard, said research tube alternates, generalities of sound, keep easy bias in mind.
In addition to needing 16 ohm taps, KT88 is how I selected my Cayin which I knew could use either 6550’s or KT88’s. 6 moons review sold me!
I guessed the KT88 would be a slightly more powerful KT66. Some amps offer EL34 or it’s substitutes, or a switch for a different tube type.
Next we have your ears/preferences, for a first time tube experience, a trip or two to a showroom is wise, however, you would want to hear the same input/preamp/speakers, that’s not easy.
Live near me in NJ, come on by!
In any case, what brand KT88? what in front of it, 12ax/12au or 6sn7/6sl7. Cayin my first amp with 6sn7/6sl7, and I was quite surprised at the change in sound two different makers.
Luckily I bought my tubes from Brent Jesse, he let me finish burning them in 60 hrs first, then exchange for full credit, tried a different brand at half the price, sounded twice as good!
