Why Can't Modern Tube Manufacturers Make a Proper Tube?

I won’t toss the baby out with the bath water. There are actually some terrific current production vacuum tubes as well as some not so terrific. I would not generalize. I have used current production EML 300b tubes in my SET mono blocks for many years. First pair lasted nearly 12 years with very heavy hours of use during that time. Simply splendid sound quality and zero reliability issues.

The 101D DHT tubes In my preamplifier are current production Psvane.W.E. Replica. Again, splendid sound quality and very reliable under very frequent/heavy usage. So it depends on which current production tubes one is referencing.

The amplifier’s rectifier and driver tubes are 1950s vintage. Same era (1950s) of tubes in my DAC. I’ve been very happy with this mixture of current and vintage tubes n my audio system. The sound is intoxicatingly natural.

many current production tubes are fine. some new production sound better than some old production. 

now youve learned something

@mulveling and the availability of JJ small signal tubes,  EL34...

Modern tubes are just fine. Have vintage stuff that is just that old.  

I'm generally not a fan of new production preamp, rectifiers . or 6L6s . The exceptions being Sophia Electric 6SN7s and 274B tubes which are very nice sounding tubes.  (haven't tried their 12au7s or 12ax7s).  I have been pleased with new production Gold Lion and Psvane KT88s , and Psvane & Linlai 845s. Not a fan  of JJ, Electron Harmoniz, or Tungsol regardless of tube type . Otherwise, I use old stock preamp, rectifier, 6L6GCs   and 7189As

@audioman58

Where can I find these modern General Electric tubes?

Thank you in advance
