A single 193M is good for starters. Place the choke on the primary side of the JR filter at the iec socket.

For a future upgrade you can look at adding another 193M to the primary side of the isolation transformer, assuming the JR filter is installed on the secondary. The trick to this type of filtering is to balance both sides of the equation. So if you have a choke on the primary side of the iso trannie, then a choke on the secondary would balance the circuitand create a very nice power conditioner. You may want to try the set up with and without the JR filter in the circuit. I prefer the sound of the choke compared to added RFI filters.
