[TenTec] Omni VI Audio Gain Taper

[phil florine]

I have an Omni VI, manufacturing date of '94.  Does anyone know the best 
way to make the gain more linear across the range of this pot?  I have used 
two Omni VIs having the option 3 upgrade and don't remember this being an 
issue, but I didn't check their date of manufacture.  A new 6+ I tried has 
the linear taper I'd like to have on my rig.

TT told me they don't have a fix for this.  They also told me that the 
option 3 upgrade wouldn't change the taper.  I briefly scanned the 
schematics for the 6+ and noticed, I believe, some resistor values 
different from those on my schematic.  

Any help from those with experience in this area is appreciated before I 
start digging around on my own.

Also, the pot is getting really noisy in the range where it is used, either 
from wear or dirt.  Any experiences here?

Thanks,

Phil, K0UBC
