    I'll be there Luther. Simply outstanding work, as usual.

    I'll shoot you an email with my current inventory, see what I might bring, and what I might leave behind.

    Cheers,
    Russ

    About 2 watts per channel into 8 ohms. Flea power but plenty for a headphone amp or pushing my Altec A7's (104dB)

    It'd go to 99db :D

    or as loud as a pair of 88db's getting ~13watts

    How does that work luther, with the tube being a dissimilair triode?

    I see plate dissipation on 1 triode as 1 watt, the other triode 10 watts, both running Class A (single ended).

    2 watts is more power than most people think, esp since tubes don't hard-clip like solid state does. I use my 6197 'Spud' Single Ended Pentode amp at the office, hooked up to my 87db Norh 3.0's, and it's more than enough for that setting. I MIGHT turn it up halfway on occasion (mind you there is no preamp stage 'push' either, just a CDP straight to the amp, through a simple volume pot on the inputs.)

    Cheers,
    Russ

    Wow. Gorgeous, and I'm sure equally wonderfully sounding, amp. 104db!! :eek: That's amazing!

    ND13, even though it'd get to 99db, using all it's watts to do that, I would think that's not a lot of room left for headroom.
