Being deaf now I have not bothered to put Patches' sound system back together in about two years as it was being used in the TARDIS console. I wired up two new 12 buttun remotes to the system and changed the programing code back to R2-CM's configuration.
The new sound remotes are installed on Patches' main transmitter.
Here is a short video of Patches back with his other three Astro brothers. :)
