   So I've decided to buy two brand new JJ's GZ34 for my two mono 2A3 amps.   
   JJ's are cheap and I thought that if they were to last a few months   
   before selling the amps they were good enough.   
   I replaced the old chinese Golden Dragons (5AR4) and everything worked   
   flawlessly. The sound was a bit thin but I thought it was just matter of   
   waiting a few days for the tubes to express themselves better.   
   Then when I was going to leave everything as it was and replace the amps   
   with the love of my life the Dynaco ST35 ...   
      
   A friend stopped by with a bag of old Mullards GZ34 to put in those amps   
   and the something really strange happened.   
      
   I always prefer double blind testing, I'm an atheist, I don't believe in   
   cable magic or snake oil or in Bolduc's mystical runes and I trust my   
   ears more than my eyes.   
      
   The difference between the sound with the JJ's and the one with the   
   Mullards is so clear that even being in another room you could feel the   
   change. Dynamics, bass response, sweetness ... I was stunned.   
      
   The difference when we tried to swap the humble Guiguang monoplate 2A3Bs   
   with the pricey AVVTs was almost inexistent apart from the latter being   
   too metallic and so the worst of the two. Great difference was achieved   
   instead when we tried a couple of Marconis NOS.   
      
   Further investigation with the use of a scope and a signal generator   
   showed that with the Mullards the sag was less and recovery was faster.   
      
   Would a couple of solid state rectifiers with a properly calculated   
   series resistances and maybe a standby switch act better than the mighty   
   Mullards?   
      
   The 35 is still on a shelf waiting ...   
      
   Are there any brand of GZ34 or 5AR4 that resemble the sound of the   
   Mullards or in other words that act electronically like Mullards?
