[R-390] Z-503 replacement & R-542 value

[Chip Owens]

Some archive info on the value of R-542 suggests 470 ohms instead of
the original 2.2K-ohm value.I'm curious about this. How does decreasing
the value of a de-coupling resistor improve performance? The archive
info is a couple years old. What is the current thinking on the value
of R-542? And what performance improvement is achieved by decreasing it
to 470 ohms?

I'm replacing Z-503 (the hard way) and since I'm in that part of the IF
chassis I thought I'd replace any out-of-spec component at the same
time.
