    I just got an Alembic FX-1 which I love. ( Sounds like butta!) I was wondering if anyone has experience with swapping tubes in this pre? Which brands/types sound the best?

    I did searches but couldn't come up with anything conclusive. Any tips/experiences with this pre would be very helpful.

    Well, tubes are pretty subjective. If you're willing to shell out megabucks for an NOS tube, I'd try an RCA, Mullard, or Brimar. For current production tubes, I like the sound of a JJ (some of the older ones are a bit noisy, but the newer ones are much better). Stay away from anything made in China!

    If I remember correctly I put a NOS Sylvania in mine and it worked real nicely.

    It's kinda fun to try several of the NO$ but I agree, the new JJ's aren't all that bad. I've got one in my Fafner.

    I haven't tried the Tesla's. I would recommend that you start a bit cheaper and go up from that. Just my two cents, for what that's worth.
     
  7. Here's a recent thread on 12AX7 tubes that you may find useful. But it really comes down to personal preference. Buy from a dealer that tests their tubes before selling and try a few of the new production tubes. A lot folks like the either the JJ or EH (electro-harmonix). If they don't work out, then try get some recommendations for NOS (new old stock) tubes from a reputable dealer.

    Besides the tubestore you mentioned, I've had good luck with with these folks:

    I think that it's a good starting point. You sure can't beat the price. I'm actually impressed with the quality of these tubes. And I have a buttload of NOS tubes.:eek:

    I'd say that the JJ should serve you pretty well. Doug was great to deal with, and after trying out a bunch of other tubes (see the linked thread, above), I probably would have been quite happy with either the JAN Phillips 12AX7, the Telefunken ECC83 (smooth plate) or the JJ ECC83S.

    Caution: do not expect a radical change - unless something was wrong with your first tube. The differences are fairly subtle, at least among fully-functional, non-microphonic tubes.

    Have fun!
