12AX7 Tubes...

post #1 of 6

Can someone list other designations for these tubes?

Are they the same as a E 88 CC, etc.?

For my EAR 834P phono amp, help please!

ECC83 is the European designation for the 12AX7:

ECC83, 12AX7, 12AX7A, 7025, E83CC, E803CC, B759, 6681, 5751, 7729



E88CC would be a 6922 which is similar to the 6DJ8 or 7308:

ECC88, 6DJ8, 6922, E88CC, 7308

5751's are generally compatible. i think 7025? or 70xx something or so is a "high performance" version of the 12ax7. anyone know if i got the numbers right? and there's CV4004 i think too.
