Beware of this mod. I got lots of trouble
when i tried changing those 1k resistors
to 4k7. It messed up the board. Canton 4.2
already has too much gain. I used only
the specified components and my problems
were solved when i undid the mod. and
added a pot to decrease the amplitude of
the video input.
