    Howdy;
    I have an eden Navigator I like a lot…except for that using the tube character control in anything but “off” results in a truly horrible to me gritty grindy fuzz nastiness. I think the unit was made in about 1997? Perhaps it’s time to replace the preamp tube…I was hoping someone could recommend me a nice fat warm clean preamp tube that would just get fatter and warmer as I dial up the tube control, instead of getting all gritty and nasty?

    Thanks, alan
     
  2. Chef:

    I'm the one who sold you the navigator. FYI, (if you didn't already take it apart) I put in a JJ's 12AX7 about a year before I sold it to you. When I bought it, it had a gorrve tubes 12AX7 in it.
    I hope any of this info helps.

    Huh, thanks...I would think the JJ tube would meet my criteria...maybe I just don't like the tube control function then?
     
  4. I used to run the tube at about 12:00 and the enhance(suck-o-meter) at about 9:00.

    It sounded good with my sterling and thumb at those settings, at any level of volume.

    To be honest, the Navigator is one preamp that to me, sounds virtually identical with any properly functioning tube. I tried a ton, and ended up just leaving the stock bottle in there. But, it sounds like maybe something has gone wrong with either your tube or your preamp. Try swapping out another 12AX7 (any kind) and see if this sound goes away. Your tube may have taken a jolt and become microphonic.
