    FM-3 tube sub

    Post by denny9167 on Mon Mar 05, 2012 11:48 pm

    I've been doing some research on tube subs for
    The FM-3 in order to help boost performance, especially
    The RF section looking at the 6AQ8, and noticed that a
    6DT8 was a recommended sub, and also noticed it
    Has a slightly greater amplification factor, has anyone tried
    This, I would also direct this to Baddog, I know he's re-built quite
    A few. I've seen other mods, one that modifies the RF section
    Using a 6DJ8 in place of the 6AQ8 w/ some curcuit mods.
    Thanks
