6DJ8 / ECC88/ 6922/7308 Tube List 

  • 6DJ8 / ECC88 is the "standard grade" of this family.  They normally have steel pins.

  • 6922 / E88CC is a "premium grade" version of the 6DJ8.  Most have gold plated pins, but many Sylvania manufactured 6922's have steel pins (a few Sylvania's are gold pin). 

  • 7308 / E188CC is generally the highest quality tube in the 6DJ8/ECC88 family.  Most have gold pins.  Sylvania's are steel pin.  They are designed with low microphonics and low noise.  Sections are usually pretty closely matched.

  • 7DJ8 / PCC88  These are 7 volt filaments which were designed to be used in series string circuits.  However, they work well in standard 6DJ8 circuits and can generally be used as direct substitutes.  You can some some money using these.

  • CCa  This is a special version of the 6922 / E88CC which is usually only found as Siemens or Telefunken.  These are very rare tubes and usually not in stock.  But as for everything else, call or email to make sure.
