musicians swear by the superior quality of vacuum (tube) amplifiers.
in Europe, tubes are called Valves.

lostiaz, for me too... my dad used to make me explain how the television worked before I could watch cartoons on Saturday mornings (I was in kindergarten)

Most people think vacuum tubes are hard to find, but go to an amateur radio swap meet sometime. They don't 'go bad' nearly as much as people think, either.

JasonR1972, Not just musicians, but audiophiles too. Some even prefer the"warmer" sound and transition free playback of vinyl over anything digital. Digital in itself will always have transitions; it's just too fast now to be audibly detected by the human ear.

quicksilver, Really the good old days when we fixed things that broke. My dad had a machine that tested the tube and for a while sold replacements.

Vacuum tubes were (and are still) used in electric guitar amplifiers, y’know! Lest we pretend this is some dead enterprise as of the 1950s or something 😂😂😂
