    SP9 & SP12 preamp builds

    Post by tubes4hifi on Thu Apr 21, 2016 8:08 pm

    I just finished building an SP9 + PH12 preamp for a customer, it's been awhile since I've done one of these,
    so figured it would be a good idea to do a photo documentation of the build, very helpful to future kit builders of
    not just this particular preamp, but any of the VTA preamps, since they are all similar builds other than the actual PCBs.
    Turns out the SP9 has more wiring than any of the other preamps, but still this went pretty smooth, about 8 hours total time.
    Here's a link to that page . . .

    Also did an SP12 build last year, did the same kind of photo documentation on it,
    so here's a link to that page for anyone doing an SP12 . . . . .
