    I recommended it to a friend. Went to the website and it's gone?
    Only SP-6 and SP-9's now?
    Will the 8 be back?
    It's a great little preamp!

    I ran out of SP8 boards, it was my most popular preamp for about 5 years.
    But I've got way too many other choices.
    The exact same circuit is now on the SP10 without phono, add the PH6 and you'll have the exact same combo as an SP8.

    Ah, thanks Roy!

    Question, do the PH-6 and SP-10 share a powersupply or is one needed for each?
    And, if two supplies, can they share a torroid?
    Obviously they did on the SP-8 and that's why I ask.
