I was over at my local amp tech shop and he was bemoaning the high number of faulty new tubes on the market. Considering the extremes some of us go to in the search for tone and the fact that tubes definitely have an impact on tone, why no US tubes? I would think somebody could create a boutique US made tube company that would appeal to the TGP crowd. Is it just not economically feasable? Is it US government and or enviromental regs that are preventing this? I would think a quality tube maker could pretty much name their price.
