I believe this is only for samsung tuners.
See here:

In the kernel file

drivers/media/video/tuner-types.c

with the +4 the amp is on without it the amp is off. If you want to test you
can update your kernel and compile ( no clean or mrpropper is necissary)
then modprobe -r ivtv  then modprobe ivtv. you may have to do the same with
tuner but I believe when I tested this on 11-11-2006 that was all I needed
to do.
