The resistor

is just making sure that the power supply looks like a straight line on the 'scope.

If you decide to install a choke instead, before drilling any holes fire the amp up and put a high level signal through the voltage amplifier (amp on Standby IOW) and see what sort of noise is present on the filter caps feeding the voltage amp, using your choke instead of the resistor.

I think though that what you will find is that the CCS in the voltage amplifier is more important than the power supply. If you look at its design, it is built to reject power supply noise.
