I suppose his point was that the professional downturn in demand will cause tube companies to go out of business? Have I got that logic right, Ralph? So all that will be left will be the remaining supply that guitar and other pro applications don't need? And that the tube makers will now be only boutique and/or very expensive?
I can't quite figure out why tubes will be going away or getting scarce on Ralph's reasoning but am interested to learn.
@hilde45 you have the reasoning right. Guitar amps are 90% of the global tube market and have been for decades. The war in Ukraine has not helped as it has caused tube prices to increase quite a lot recently. Right now its not too much of an issue, but even in high end remains the simple question of what if a solid state amp comes along and sounds better than the tube competition?
I enjoy tubes quite a lot. I like to devise circuits for them and build projects, just for the fun of it. Its made me keenly aware that some of the appeal of tubes has an artisan quality about it.
