Amperex "Bugle Boy" tube compatibility

I need to replace a vacuum tube in a pre-amp section of the integrated amplifier as the previous tube Beijing 6N11 went bad. The Amperex "Bugle Boy" ECC83/12AX7 tube has the same pin layout as Beijing 6N11 tube. According to description on Amazon the Beijing 6N11 may be used instead of ECC88, E88CC, 6922, 6DJ8, 6922 and 7308. Would it be okay to use Amperex "Bugle Boy" as a substitute to Beijing 6N11 tube?

No.
12AX7/ECC83 has very different pin out from any of those tubes you have named that are said to be compatible with the 6N11. Things equal to the same thing are equal to each other. Things not equal to the same thing won’t work. Furthermore, the electrical characteristics of a 12AX7 are also very very different from any of the tubes you listed. In other words, you would not want to replace a 6N11 with a 12AX7, even if you could.

From your description,  No.  The E88CC, 6DJ8 family of tubes are 6 volt tubes and the 12AX7 are 12 volt.  It shouldn't be hard  to find tubes of the E88CC, 6DJ8 family.

Actually you can run a 12AX7 with a 6V filament supply. In this case it would only require some re-wiring of the tube socket. But that’s the least of the reasons why not to do it.
