Re: the holy grail of tubes
this is why I make amps that sound good with new production tubes. if in 20 years you can't find NOS tubes (and you probably won't for less than LARGE jack), you'll still be able to play my amps.
i'm more concerned with the new sensor problems they are having with that russian real estate developer (mafia?) guys and their plant there. Hopefully it gets worked out to our favor as guitarists. Otherwise, russian tubes might be a thing of the past.
