Hello everone,
Is it possible to upgrade my 3 port SNA (a/b/r) to a 4 port SNA by just replace the frontpanel or do in need some other changes?

You'll also need an additional log amplifier assembly (A9) in order to add an additional channel as shown in the service manual.
I'm not sure if any additional configuration or different firmware is required to get this to work either.
