The E88CC (6922) is a variant of the 6DJ8 that the aune T1 uses. This amp will take 12AX7 (ECC83)
as to will it work... probably not. The 12AX7 is rated for 250 Va (volts at the anode) whereas the E88CC is rated for 90. Unless they are seriously underdriving those tubes they'll likely blow the E88CC in a few hours.
They are also likely using a 12.6V heater, which is much too high for the E88CC, though if they're running a lower voltage (which is still within the range for 12AX7, it could in theory work.
TL;DR: Most likely won't work. Don't try it.
so you mean e88cc rigs will run ecc83/12ax7? but not the other way around(as in this case)
