There's been some big changes in my vintage Altec 832A Corona based bedroom system recently.

One of the favorite pastimes of many original Leben CS-600 integrated amplifier owners has been trying different combinations of vacuum tubes in their CS-600 to tailor its sound to what best matches their personal taste.
