The main supply issue facing audiophiles is for power tubes - especially the big types for which there is no NOS / vintage alternative in quantity. The situation is especially dire for amps designed around KT120 and up (especially 150, 170).
this is true... but as also mentioned, the tube plant making these is indeed running and the tubes will just travel a more meandering route to the find end users needing them (just like russian fishing output, going through china processors on their way to costco...)
... and for users who are using high-spec amps running these tubes, i would guess they can afford an upcharge -- (reminds me of when porsche owners complain about the price of gas... not much pity should be offered, nor expected... 😁)
