I got it. And I've played a 1905 Martin and you can still plug a 1950s telecaster into a 1950s amp in turn plugged into wall power and everything works. Just saying, that is not the consumer electronics world in 2026.
A replacement set of tubes for a 1950s Fender amp costs $200-$400 today, just for parts. A lot more than a new Kindle. A Kindle might even be less e-waste than a set of tubes too.
