    Hi All,
    =20
    In case anyone else is disenchanted with the general "feel" of the =
main tuning knob, I did lots of experimenting to improve it. Had great =
success. This remedy also works exactly the same on the uneven drag on =
the TS-950SD knob.
    =20
    The OMNI-6 adjustable drag mechanism is rather mickey-mouse in my =
opinion. It can produce an uneven amount of drag during one revolution. =
This annoyed me to no end. (It was  worse on my "spare" rig: TS-950). It =
also would produce a slight screechy noise from time to time, even =
though I spread teflon lube on the rubbing plate behind the felt-padded =
bronze arms.=20
    =20
    So, I played "operation" and performed the following "final =
solution:"
    =20
    1...take knob off and take the bronze arms off.
    =20
    2...bend bronze arms backward from the way they were.  Now, when you =
re-install the screws, they will apply tension to the skirt, locking it =
permanently in place.
    =20
    3...apply a coating of rubber cement to the inside, back of the =
knob. (If you use the type of rubber cement such as is intended for =
gluing paper with, it can be removed by rubbing it with your finger, in =
case you should chicken out from the project).
    =20
    4...while cement is wet, press a layer of cotton, from a pill =
bottle, to the cement. You can remove some of the cotton a little at a =
time to adjust distance from the skirt to panel after the cement dries, =
so a lot of cotton is OK for now.
    =20
    5...apply small amount of teflon lube (Radio Shack precision lube =
pen) to the plastic friction rubbing surface on panel behind the knob. =
Re-install the knob.
    =20
    6...the drag adjustment is now accomplished by adjusting the =
distance from knob to panel. Coarse adjustment for final distance is =
made by removing some cotton.
    =20
    7... Wow! The tuning knob now feels like silken velvet. Just =
perfect, and it has  an even amount of drag all the way around a =
revolution. I prefer mine with very, very light drag.
    =20
