    I just got my SP-8 preamp up and running and it sounds great. But continuing with my philosophy of "Not leaving well enough alone", does anyone have suggestions on what resistors to upgrade. I have ordered the upgraded power supply caps from Roy already but need something to do until they arrive.

    Thanks

    When I get it all wrapped up and looking pretty. Right now there is to many wires running all over the place.

    don't forget there is a build thread (about 5 pages worth with LOTS of photos) posted on this posted
    on my website here: www.tubes4hifi.com/SP8-AM1.htm

    Thanks, I had forgotten about the build page. This happens when I start a project and don't get back to it until the next year.
