Re: Tube amp with headphone jack?
Using the availability of a headphone jack as a way to help choose a tube amps seems kind of arbitrary. So few tube amps have headphone jacks that you're likely to be eliminating an amp you'd otherwise love just for the sake of a headphone jack. You'll probably be a lot better in the long run if you get a tube amp you really like for loud playing and something like a POD or GuitarPort for headphone practice.
Remember, most headphone jacks get their signal from the preamp, not the power amp, so it's not like you're even using the power tubes. Doesn't that somewhat defeat the purpose of having a tube amp?
