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.
Follow Ups:
Was just trying to give Cousin Billy something to do. I know what it's like to get the itch.
This is the choke already in the amp.
Who knows it's value's?
The choke we see is paralleled with the 200uF cap.
I will assume any new chokes will attach as the resistors are attached?
I doubt that it is in parallel with a 200uF capacitor; more likely the capacitor is in parallel with the output from the full wave bridge rectifier, and the choke is in series with the FWBR. But as to value, I am sure Ralph can help.
