If you are ever down south, the Seaford Martello tower museum is well worth a visit. For a start it has a good display of valve radios and a few TV's, including some quite rare items. However, it doesn't stop there and you will find pretty much every early 20c household item you can think of on display mostly in period room settings. More than enough to keep you entertained for an hour or two, have a look through the many slides as you will be amazed at just how much you can store underneath a little Martello tower.
