Another problem with tube amplifiers is heat. They generate lots of heat. A power tube puts out the heat of an old-fashioned incandescent light bulb. The average stereo tube amplifier has four of these. It is not unusual at all for audio freaks to have two sets of amplifiers…tubes for the winter and something else for the summer. It is that much heat. I had a girlfriend once burn down her apartment with a tube amplifier I once lent her, a lovely old Harman Kardon. She left it on, and left to go shopping. The curtains blew across it. Whoosh!
