You must have a huge house!
My TV's are scattered round my house, workshop and garage, the lounge is currently home to nine sets, which have been restored, or are in lovely condition. The ugly and tatty sets take up one side of my workshop, while six small sets are currently stored in my loft/radio museum, and the rest are piled high in one of the bedrooms.
I am slowly converting my large garage in to a dry and insulated space to house my TV collection, which is still growing
I now restrict myself to single channel sets only, although I do have a few later sets, but these are still valve powered.
Like Lloyd, I would like to set up a distribution amp for feeding multiple sets once the garage is completed, and move my workbench and test equipment down one end, freeing up my present 10x8 workshop for storage.
