I've got and old Audio Research VT130 amp that was kind of "thrown in" on a purchase I made some years ago. It had a blown screening resistor (that kept blowing thanks to a failing 12BH7 tube that tested OK) I replaced a number of resistors and bought a matched tube set for it from ARC ($2100 GULP). The 'ol girl just sounds so warm and sweet with such a silent black background that I just keep finding "second location" systems to include it in. For now it's job is to make a pair of Maggie 2.7s sing in my small office. It doubles as a space heater in the winter and smells wonderful when it's warmed up.
I suppose it's true romance.
