    Here's a source of both info on tubes, and for purchases:

    Not affiliated in any way, except that I plan to purchase some 12AU7/ECC82's for my Candela linestage.

    I've read that his reputation is good though.

    Thanks for the link, but after reading the FAQ on that site I'm still not sure if I need to reset bias when installing the new 6N1P-EV's, I am keeping the stock EL34B Output tubes.

    Bias is only for power tubes, you won't set the bias for signal tubes like driver and pre-amp tubes.

    That's not to say you shouldn't rebias the power tubes if you are using a different driver tube, but if the driver tube/pre-amp tubes are similar in gain, etc you won't need to rebias.

    "Appreciation of audio is a completely subjective human experience. Measurements can provide a measure of insight, but are no substitute for human judgment. Why are we looking to reduce a subjective experience to objective criteria anyway? The subtleties of music and audio reproduction are for those who appreciate it. Differentiation by numbers is for those who do not".--Nelson Pass Pass Labs XA25 | EE Avant Pre | EE Mini Max Supreme DAC | MIT Shotgun S1 | Pangea AC14SE MKII | Legend L600 | BlueSound Node 3 - Tubes add soul!
