Hi Everyone,

Does anyone know the diffence between these 2 Shuguang variants of the 5Z4? My monoblocks uses 2 rectifiers in each channel. Can I use 2 5z4pa in one channel and 1 5z4pa and 1 5z4p in the other?

the "PA" seems to be an uprated version of the "P" --- rough Kanji.

  HI Fenderlover,
  
  Is it ok to use the 5z4p with the other 3 5z4pa?
  
  Or would it be advisable if I just sourced for another 5z4pa?
  
  Thank you for your help.

    I'd source another 5Z4PA.
    
    Good luck!

      Hi Fenderlover,
      
      Thank you for your help. I am a tube noob here...will it harm my monoblocks if I were to use the 5Z4P in the interim til I source for a 5Z4PA?

        One monoblock will have a 5Z4P and a 5Z4PA? I don't think this will harm the amp, but overall tonal response may suffer. Why not just get a new "PA" ?

        Hi Fenderlover,
        
        Thanks again for your advise. Really appreciate it. One monoblock will have two 5Z4PA and the other monoblock will have one 5Z4PA and once 5Z4P.
        
        I bought a quad of Sovteks 5AR4 to replace the Shuguangs and I did not like the sound. Overall presentation "lifeless". That's the reason why I am going back to the Shuguangs. Reason why I changed to the Sovteks in the first place was that one of the Shuguangs 5Z4PA failed.
