K2 Audio control scratchy throughout the range

Andrew Catanzaro
I inherited a second K2.  It is serial number 85 and works very well
except the volume control is noisy and erratic throughout its range.  Do
I need to do anything other than replace the pot?  I know there were
other mods for the volume control and its circuit, but I believe it was
because of noise only on the low end of the range.  I think this pot is
just plain old and the radio sat unused for the last seven years.

Thanks!

Andy,

Replace the AF Gain pot and install the Alternate AF Gain Wiring Mod
