Mr. Part of your description is incorrect.
System II is pins 1,2,3 and is the AU7 (lower gain)
this triode is usually wired as the first gain stage
System I is pins 6,7,8 and is the AX7 (higher gain)
This triode is usually wired as the second gain stage.
The JJ 823 is internally configured opposite.
The tube names confused me at first as well, but the datasheet describes the configuration.
I am a customer of MojoTone, great service and delivery.
My orders have always been correctly filled and on time.
